Foreword
2009 was a busy year at the Sterrewacht. The institute's permanent
staff saw some important changes, with the arrival of Xander
Tielens at the beginning of the year, Simon Portegies Zwart in the
spring, and Matt Kenworthy at the end of the year, and the
appointment of Rychard Bouwens (who will arrive during 2010).
Xander moved to Leiden from NASA-AMES, and takes up a chair
in interstellar medium physics and chemistry, and will further
strengthen our astrochemisty research. He won an important grant
from the European Research Council with which he will build up a
significant group.
Simon Portegies Zwart moved here from Amsterdam, and is our
new professor of numerical astrophysics. His work centers on
gravitational dynamics of star clusters and galaxies, and involves
using dedicated specialized hardware such as GRAPE boards and
Graphical Processing Units. He obtained a VICI grant for his
research, and leads a large NOVA project on computational

astrophysics, AMUSE. A third new professor is Huub Rottgering,
who was promoted from his senior lecturer position.
Matt Kenworthy joined us from Steward Observatory in Arizona,
and specializes in astronomical instrumentation, especially
adaptive optics, for exoplanet research. He takes up a position as
lecturer. Rychard Bouwens, from the University of California at
Santa Cruz, an expert on high-redshift galaxy studies with Hubble
Space Telescope in particular, accepted an offer of a lectureship
with us and will start in 2010.
A small symposium was held for Peter Katgert in September. Peter
retired after some 40 years on the faculty at the Sterrewacht, and
handed over his careful stewardship of the Leids Sterrewacht,
Leids Kerkhoven Bosscha, and Oort foundations as secretarytreasurer to Michiel Hogerheijde.
The support staff underwent many changes as well.
Jan Lub stepped down as institute manager after many years, but
will still be around to provide his successor, Evelijn Gerstel, with
the benefit of his memory and experience. Evelijn moved to the
Sterrewacht from the physics department, where she had been
coordinator of the education activities. The Sterrewacht's education
coordinator, Petra Oosthoek, moved to the Computer Science
department. Finally Kirsten Groen, who has been a member of our
secretariat for the last 10 years and has ably assisted me and my
predecessor as management assistant, decided to move full-time to
the NOVA office as financial controller, and her work was taken
over by Jeanne Drost. In spite of all the changes, the handovers
were smooth and somehow everything continued to run the way it
should, in large part due to the dedication of all concerned. My
thanks!
REVIEW OF MAJOR EVENTS
3
The most significant events of the year included the launch of
Herschel, the successful refurbishment of Hubble, the first images
from VISTA and the first maps from LOFAR: we have major plans
for all these facilities and first results have already been obtained.
These highlights underscore that we owe much of our scientific
reach to the facilities we have access to, and have a role in
developing, in collaboration with organizations and institutes such
as ESA, ASTRON, ESO, SRON and our sister institutes in NOVA.
Continued involvement in developing the facilities of the future
will ensure that we keep on creating such scientific opportunities.
2009 was the International Year of Astronomy, and under this
extra spotlight a number of prominent activities took place. Ewine
van Dishoeck was the lecturer at the university's dies natalis on
February 9, speaking on "New Worlds". The 20th Oort lecturer was
Bruce Draine from Princeton, and Jerry Nelson (Santa Cruz)
delivered the Sackler lecture in the fall. The old observatory
building's renovation was started, with the first of the domes
hoisted off the building by minister Plasterk of education, culture
and science on April 6. Everything seems to be on track for the old
observatory's reopening in 2011.
11 graduate students successfully defended their thesis and
obtained their PhD, a near-record: but with around 50 PhD
students at the observatory now, we will have to get used to this
rate! Our graduates continue to do well on the international job
market, with the Hubble Fellowship for Karin Oberg, and the
Jansky Fellowship for Huib Intema, as most impressive examples.
Finally, a sad piece of news that reached us during the year was
the passing of Maarten Floor (1917-2008): he worked at the
Sterrewacht as a 'calculator' from 1955 until his retirement in 1980.
I imagine he would have been quite amazed at the calculations we
now take for granted.

REVIEW OF MAJOR EVENTS
As I write this introduction, preparations for a research assessment
in the spring of 2010 are in full swing. We are working hard to
ensure that the Sterrewacht (as well as the rest of NOVA) will
come through this process with flying colours, and given the many
results and achievements described in this annual report there
certainly are plenty of reasons to be optimistic!

History and heritage
The Sterrewacht acts as host to the history group of the Leiden University
Department of Mathematics and Science.
Van Delft (director Museum Boerhaave), holding a part-time appointment as
professor extraordinary in the history of science, focused his research on the
Leiden cryogenic laboratory, the international temperature scale and the
International Institute of Refrigeration.
Van Lunteren, also holding a part-time appointment as professor extraordinary,
conducted studies on 19th- and 20th-century Leiden scientists which resulted in
three papers: one on the astronomer Kaiser as a Dutch pioneer of the new genre
of popular science, one on the cultural roots of the views of the physicist Fokker
on causality and time symmetry, and finally a study, together with Hollestelle,
of the Austrian-Dutch physicist Ehrenfest.
Elbers is studying the rise of radio astronomy in the Netherlands in the post-war
years. Her research is predominantly based on primary sources in the Oortarchives and in those of the Observatory itself. It focuses on the interplay of the
personal and as well as the more general factors that may serve to account for
the successful launch of this new research field. She presented preliminary
results at the meeting of the History of Science Society in Phoenix and
constructed a general framework for her PhD-project. She also located several
other relevant archival collections.

2.1 SOLAR SYSTEM
Weiss studied the archives of the Teyler's Museum in Haarlem in order to
reconstruct the changes in both the public and research functions of this
institution. He unearthed previously unknown documents concerning the
Teyler's Museum 19th- century collection policy. He also systematically
compiled the accounts by visitors of their experiences at Teyler's Museum from
the early decades of the museum's history. Finally, he initiated and organised a
national conference on the public usage of 19th century Dutch collections which
will be held in 2010.
Baneke completed his inventory of the paper collections of Frederik Kaiser and
Willem de Sitter, being the two major constituents of the Leiden Observatory
Archives. These archives were transferred to Leiden University Library for
preservation and digitalization. He also completed a research project on the
history of Dutch astronomy in 1880-1940, analyzing changes in the scientific
culture, the introduction of new educational programs at Dutch astronomical
institutes, and the remarkable renaissance of Leiden Observatory in the 1920's.
2.1. Solar System
2.1.1 Asteroids
After sixty years of minor planet (planetoiden in Dutch) research I. van HoutenGroeneveld and her late husband C.J. van Houten, the former is still actively
continuing her work. The new names of minor planets and the lists of new
definitive numbered minor planets of the van Houten sample are published in
the Minor Planet Circulars (MPC), which come out monthly at full Moon.
The van Houten Palomar-Leiden survey plates are now at Heidelberg
Sternwarte (Germany) in the custody of L. Schmadel (Astronomisches RechenInstitut). All short-exposure plates of P-L-survey and all Selected Area plates
have now been measured: 36 187 individual positions of 4 906 different objects.
The P-L-Survey contains the following numbers of objects: 2124 found, 242
found by other observers, as well as 2540 new ones found by Schmadel of which
1817 are numbered, and 723 are provisionally named. By using overlays of all
2008 known minor planets and extrapolating back to the P-L-plate epoch of
1960, Schmadel found the positions of significantly more objects than the van
Houtens originally found. This means 52% pre-discovery-objects were found!

In 2008 and 2009, 2093 van Houten survey minor planets were definitely
numbered, five of them being Trojans. In the same year, 40 received names
following proposals communicated by Van Houten-Groeneveld. Eleven names

2.2. Exoplanets
Figure 1: Artist impression of the changing phases of extrasolar planet CoRoT-1b, as
detected by Snellen, de Mooij, and Albrecht. The phase variation is just as we see it for
the interior planets in our own solar system.
2.2 EXOPLANETS
11
2.2.1 Eclipsing Exoplanets
Snellen and collaborators worked on the detection and characterization of
transiting extrasolar planets. Most of the more than 200 known extrasolar
planets have been found using the radial velocity technique. Although their
orbits are well known, not much is being learned about the planets themselves.
This is very different when the orientation of a planet is such that it transits its
host star, regularly blocking off a fraction of the star light. For these planets, the
mass, radius, and average density can be determined, and their atmospheres
probed through secondary eclipse photometry and transmission spectroscopy.
De Mooij and Snellen presented the first ground-based K-band detection of the
secondary eclipse of an extrasolar planet. Together with Albrecht they published
in Nature the optical phase curve of an extrasolar planet using CoRoT data.
2.2.2 Metal-dependent Planet Formation
Exoplanets are preferentially observed around metal-rich stars. Rich in elements
heavier than hydrogen and helium. Johansen, Youdin (CITA, Canada), and Mac
Low (American Museum of Natural History) found a physical explanation for
this phenomenon. They performed 3-D computer simulations of the initial
stages of planet formation, varying the heavy element abundance of their disk
models. Planets form in protoplanetary discs around young stars as dust
particles collide and grow to ever larger structures, but this process becomes
inefficient on scales of a few centimeters. Pebbles of such size have very poor
sticking properties. However, hydrodynamical simulations show that pebbles
moving through gas will spontaneously form dense clumps and that these
clumps can contract under their own weight into mini-planets (called
planetesimals) of several hundreds of kilometers in diameter. Johansen and
collaborators found that the process of clumping depends strongly on the mass
loading of pebbles in the gas, i.e. on the heavy element abundance. Below solar
metallicity they observed no clumping and no planet formation, whereas
slightly above solar metallicity planet formation has become very efficient. Their
findings, summarized in a press release titled “Dirty stars make good planetary
hosts”, were picked up by several news media, including SPACE.com,
Astronomy Now, and ABC news.

2.3 Protostars and Circumstellar Disks
2.3.1 Predicting the Water in Protoplanetary Disks
Brinch completed the LIME code. This is a 3-D molecular excitation and
radiation transfer code that has been under development for several years.
LIME models radiation transfer on unstructured, random Delaunaytriangulated grids, and it produces high-resolution predictons of the spectral
emission distribution. LIME is designed to be used to model Young Stellar
Objects (YSO's) and their environments with the specific aim of becoming a
robust modeling tool for use with ALMA observations. Toward the end of 2009,
LIME was used for the first time to predict water line emission from the hot
surface of a protoplanetary disk (Fig. 2) in very high resolution. This predictions
will be verified by HIFI observations with the Herschel Space Observatory in the
near future.
Figure 2: Model prediction of water line emission from the hot surface layers of a
protoplanetary disk. The cold mid-plane of the disk is emission free because the water is
frozen out as ice.
2.3 PROTOSTARS AND CIRCUMSTELLAR DISKS

2.3.2 The Molecular Content of Protoplanetary Disks
Panič completed her PhD thesis under supervision of Hogerheijde, describing
high-angular-resolution observations of protoplanetary disks. She focused on
the molecular content of these disks, the total amount of material and its
kinematics. Panič and Hogerheijde studied two samples of objects: T Tauri stars
(roughly comparable to the young Sun) and Herbig Ae stars (their slightly more
massive counterparts). It turned out that the latter class is most amenable to
investigation through the emission of CO and its isotopes, because these stars
are brighter: they heat the disks to higher temperatures in excess of 20 K. This
precludes the freeze-out of CO onto dust grains, prevalent in T Tauri disks. In a
more detailed study of the disk around the star HD100546, Panič et al. found
that there is a significant amount of warm (typically 100 K) gas, betrayed by
APEX/CHAMP+ CO J=6-5 measurements. This gas is probably heated by the
stellar ultraviolet radiation. At the same time, this radiation must be sufficiently
'soft' to avoid dissociation of CO into C and O, as emission from the carbon atom
is wholly absent in the same data. Interestingly, the shape of the spectral line
indicates that the disk is not uniformly heated, but rather that one side 20--40 K
warmer than the other side. It is possible that the inner disk is warped, and
casts a shadow on the outer disk.
2.3.3 Ice Survey of Low-Mass Protostellar Envelopes
Bottinelli, Öberg, Boogert (IPAC, Pasadena, USA), Pontoppidan (Caltech,
Pasadena, USA), van Dishoeck, Lahuis and the ‘Cores to Disks’ (c2d) IRS team
completed their Spitzer + ground-based 3-38 micron spectral survey of 41 lowluminosity young stellar objects (YSOs) down to proto-brown dwarfs. Their
fourth paper addressed the solid NH3 and CH3OH abundances, both of which
are key ingredients for making prebiotic molecules in ices. Identification of
these molecules is complicated by the blending of their main features at 9.0 and
9.7 micron with the strong silicate absorption band (see Figure below), and
different methods had to be developed to extract them. The resulting NH3
abundances were between 2 and 15%, whereas those for CH3OH had a broader
range from <1% to nearly 30% with respect to H2O ice. Comparison with
laboratorium results by Bouwman, Beckwith and Linnartz showed that NH3,
like CH4, is formed largely by hydrogenation of atomic N on grains, whereas
CH3OH appears to form mostly through hydrogenation of CO in a nearly pure
CO ice environment. Quantitative simulations of the latter process were carried
out by Cuppen and collaborators using the latest Leiden laboratory data.

24 micron color image of the Serpens core.
2.3.4 Origin and Evolution of Complex Organic Molecules in Space
Complex organic molecules are ubiquitous in space. Herbst (Ohio State, USA)
and Van Dishoeck reviewed the topic for Annual Reviews in Astronomy and
Astrophysics. There is now strong evidence that the rich variety of volatile
complex molecules seen in the millimeter spectra of young stellar objects are
primarily formed in the ice mantles on interstellar grains. This chemistry
appears ubiquitous throughout the Milky Way, with remarkably similar
abundances on large scales. Öberg, Bottinelli and van Dishoeck developed an
indirect method for testing this hypothesis through two organic molecules CH3OH and HNCO - that can be observed both in the gas and in the ice. They
found a tentative correlation between the ice and gas abundances with a
measured gas-to-ice ratio of 10-4, which agrees well with predictions for the
photo-desorption mechanism measured in the laboratory by Öberg and
collaborators. This provided a proof of concept that non-thermal desorption
products in cold clouds can serve as a signature of the (complex) ice
composition.
2.3.5 Chemical Evolution from Cloud to Disk
Visser, van Dishoeck, Doty (Denison Univ., Ohio, USA), and Dullemond (MPIA
Heidelberg, Germany) developed a semi-analytical 2-D model to describe how
2.3 PROTOSTARS AND CIRCUMSTELLAR DISKS
15
material changes physically and chemically as it is transported from a collapsing
cloud to a protoplanetary disk. Thus far, only 1-D models were used but they
could not properly describe the incorporation of material into disks. The model
computed infall trajectories from any point in the cloud and tracked the radial
and vertical motion of material in the viscously evolving disk. It included a full
time-dependent radiative transfer treatment of the dust temperature, which
controls much of the chemistry. As a first application, the freeze-out and
evaporation of CO and H2O ice were studied, as well as the potential for
forming complex organic molecules in ices. A fraction of the ices in comets are
indeed expected to be pristine molecular cloud material. Material that ends up
in the planet- and comet-forming zones of the disk (~5-30 AU from the star) is
predicted to spend enough time in a warm zone during the collapse to form
first-generation complex organic species on the grains.
Figure 4. The evolution of material from the prestellar core stage through the collapsing
envelope into a protoplanetary disk. The formation of zeroth- and first-generation
organic molecules in the ices is indicated occurs at 0 and 1, and second-generation
molecules in the hot-core region at 2. Once material enters the disk, it will rapidly move
to the cold midplane where additional freeze-out and grain surface chemistry occur. All
ices evaporate inside the (species-dependent) sublimation radius (‘snow line’)

2.3 PROTOSTARS AND CIRCUMSTELLAR DISKS
2.3.6 Sun-bathing around Low-Mass Protostars
Figure 5.Spitzer three color (3.6 (blue), 4.5 (green) and 8 micron (red)) image with the
contours of integrated CO J=6-5 emission (blue/dark) observed with APEX-CHAMP+
overlaid. The [C I] 2-1 emission (green/light) is detected weakly on source but peaks
further down at the tip of the outflow where the UV photons produced in the fast bow
shock are hard enough to dissociate CO. Analysis of the line profiles shows that the
emission consists both of accelerated swept-up gas along the outflow as well as quiescent,
photon-heated gas surrounding the outflow cavity walls.
Van Kempen, van Dishoeck, Hogerheijde, Kristensen, Yildiz, Guesten (MPIfR,
Bonn, Germany) and collaborators used the new CHAMP+ camera on APEX to
image CO J=6-5, 7-6 lines, as well as lines from isotopologues and [C I] 809 GHz,
in a dozen low-mass protostellar sources on scales of several arcmin to probe the
origin of warm gas in their surroundings. Such studies have only become
possible thanks to the development of heterodyne arrays at high frequency
combined with an excellent site. Surprisingly strong quiescent extended
emission from narrow high-J 12CO 6-5 and 7-6 lines is seen toward all protostars,
suggesting that heating by UV photons along the outflow cavity dominates the
emission. The UV photons are generally not energetic enough to dissociate CO
since the [C I] 2-1 emission, also probed by our data, is weak except at the bow
2.3 PROTOSTARS AND CIRCUMSTELLAR DISKS

shock at the tip of the outflow. Shock-heated warm gas characterized by broad
CO line profiles is seen only toward the more massive Class 0 outflows. This
shocked gas is also revealed through Spitzer maps of the pure rotational lines of
H2 in the NGC 1333 region in a complementary study led by Maret (Grenoble,
France) and involving Kristensen.
In collaboration with Bruderer, Benz (both ETH, Zürich, Switzerland) and Doty
(Denison Univ., Ohio, USA), multidimensional chemical models have been
developed which can tackle the physical and chemical structure of irridiated
outflow walls. The initial application has been to high-mass YSOs, but such
models are now being constructed for low-mass YSOs together with Visser for
interpretation of Herschel data.

Kóspál, Abrahám, Kun, Moór (Konkoly Obs., Hungary), Henning, Leinert
(MPIA Heidelberg, Germany), and Acosta-Pulido (IAC Tenerife, Spain),
compiled a mid-infrared spectral atlas containing observations of 68 low- and
intermediate-mass young stellar objects. The atlas contains 2.5-11.6 micron low-
18
2.3 PROTOSTARS AND CIRCUMSTELLAR DISKS
resolution spectra obtained with the ISOPHOT-S instrument on-board the
Infrared Space Observatory, as well as 5.2-14.5 micron low-resolution spectra
obtained with the IRS instrument on-board the Spitzer Space Telescope between
2004 and 2007. The observations were retrieved from the archives and were
post-processed interactively by self-developed routines. Kóspál, and
Collaborators analyzed the mid-infrared variability on both yearly and decadal
timescales. They identified 38 candidate variable sources and characterized the
wavelength-dependence and possible physical mechanisms of the flux changes.
2.3.8 Characterization of Embedded YSOs and Disks
Van Kempen, van Dishoeck and collaborators developed a method to
characterize the truly embedded stellar population in Ophiuchus. They used the
extent and strength of a high density tracer, HCO+ J=4-3 observed with JCMT
HARP-B, combined with two column density tracers, C18OJ=3-2 and the SCUBA
dust continuum. Of the 40 candidate sources, only 17 turned out to be bona-fide
embedded YSOs. Accurate classification is essential to determine reliable
lifetimes of the various evolutionary phases. Jörgensen (Bonn, Germany), van
Dishoeck, Visser, Lommen and collaborators used the Smithsonian Millimeter
Array to characterize young disks in the embedded stage of star formation
through a survey of 20 sources. The interferometer data allow the disk and
envelope emission to be disentangled. They found the envelope mass to sharply
decrease from the Class 0 to the Class I stage, whereas the disk mass showed no
evolution between these stages. In addition, four Class I sources exhibited signs
of Keplerian disk rotation in HCO+ J=3-2 data. The inferred stellar masses
indicate that the stars contain 70-98% of the total mass in the star-disk-envelope
system, confirming that most of the material has already accreted onto the
central star at this stage. Comparison with evolutionary models showed that
these tended to overestimate disk relative to stellar masses. Thus, material
accreted from the large scale envelope has to be processed more rapidly onto the
central star by some mechanism.
2.3.9 First Results from WISH
Van Dishoeck, Kristensen, van Kempen (CfA, Boston, USA), Herczeg (MPE,
Munich, Germany) and collaborators obtained the first data from the 'Water in
Star-Forming Regions with Herschel' key program. PACS spectra and maps
were obtained for three science demonstration sources. The water molecule is a
particularly sensitive probe of where a young star dumps energy into its
surroundings. Figure 7 shows the water emission map along the outflow lobes
of the deeply embedded protostar L 1157 in a study led by Nisini (INAF, Rome,
Italy). The water emission shows up most strongly in "hot spots" due to strong
2.3 PROTOSTARS AND CIRCUMSTELLAR DISKS
19
shocks symmetrically displaced from the young star. Toward another young
sun-like star, HH 46, PACS has imaged a strong line of atomic oxygen. This line
is one of the most direct probes of the rate at which the young star loses mass.
Interestingly, the line detected by PACS shows not only the low velocity gas
swept up by the jet, but also very fast moving gas that is part of the jet itself.
This will allow a direct determination of the energy involved in both processes.

1157, lighting up the two-sided outflow of gas.
2.3.10 Spitzer c2d Census of Cold Disks with Large Inner Dust Holes
Understanding how disks evolve and dissipate is essential to studies of planet
formation. Merin (HSC Madrid, Spain), van Dishoeck, Brown (MPE, Munich,
Germany) and collaborators used the Spitzer c2d survey to identify 35 candidate
transitional disks for which IRS spectra were obtained in a Spitzer program. Of
these, 15 turn out to be 'cold' disks lacking mid-infrared excess, whereas a large
fraction of the remaining 20 are disks in which the grains have grown and
settled to the mid-plane. These statistics give a frequency of cold disks of 4-8% of
the YSO population, indicating that transitional disks represent a short-lived
phase in disk evolution. Hole sizes are generally smaller (a few AU) than for
previously discovered cold disks and reflect a distribution more consistent with
exoplanet radii. Reliable criteria for identifying disks with inner holes from
20
2.3 PROTOSTARS AND CIRCUMSTELLAR DISKS
Spitzer photometry have been determined, which can be applied to larger
samples.
2.3.11 CO Isotope-Selective Photodissociation Revisited
Photodissociation by UV light is an important destruction mechanism for CO in
many astrophysical environments. Visser, van Dishoeck and Black (Chalmers
Univ., Göteborg, Sweden) revisited this process using recent spectroscopic data
which allowed determination of depth-dependent and isotope-selective
photodissociation rates with higher accuracies. Theirs is the first such model to
include the rare isotopologues C17O and 13C17O. The results have been applied
to diffuse and translucent clouds, photon-dominated regions, and circumstellar
disks. Increasing the excitation temperature reduces the isotopic selectivity by
as much as a factor of three, whereas grain growth can enhance it by an order of
magnitude. The photodissociation rates of C17O and C18O show almost exactly
the same depth dependence so 17O and 18O are equally fractionated with respect
to 16O.This supports the recent hypothesis that CO photodissociation in the solar
nebula is responsible for the anomalous 17O and 18O abundances in meteorites.
Using the unprecedented quality of ESO-VLT-CRIRES data, high precision
measurements of C17O, C18O and C16O abundances have been made by Smith
(UCLA, USA) and collaborators (including van Dishoeck) of one disk and one
protostellar envelope as part of a VLT large program led by van Dishoeck. The
derived oxygen abundance ratios for the VV CrA disk show a significant massindependent deficit of C17O and C18O relative to C16O compared to ISM baseline
abundances, consistent with the isotope selective process in the upper layers of
the disk. The Reipurth 50 envelope shows no clear differences, as expected.
2.3.12 Crystalline Silicates in Disks
As part of the c2d legacy program, Olofsson, Augereau (Grenoble, France), van
Dishoeck and the c2d team analyzed Spitzer-IRS spectra of ~100 T Tauri stars to
quantify their crystallinity fraction. More than 3/4 of the objects show at least
one crystalline silicate feature that can be essentially attributed to Mg-rich
silicates. The Fe-rich crystalline silicates are largely absent in the c2d sources.
The strength and detection frequency of the crystalline features seen at long
wavelengths (probing scales less than 10 AU) correlate with each other, but not
with those at 10 micron (probing even smaller scales less than 1 AU). This leads
to a crystal paradox: the crystalline silicate features are detected 3.5 times more
frequently in the colder outer disk (~55% vs. ~15%) than in the much warmer
inner disk regions where the material supposedly crystallized. Thus, the need
for an efficient outward radial transport mechanism in disks around T Tauri
stars is suggested.

2.3.13 An Unbiased Disk Sample in Serpens
The Spitzer c2d survey has revealed a new population of YSOs in a previously
unexplored region of the Serpens molecular cloud. Compared with other lowmass star-forming clouds, Serpens has a much higher star formation rate per
unit volume. Thus, it is an excellent laboratory to test disk properties in a
clustered environment. Oliveira, Pontoppidan, van Dishoeck, Merin and
collaborators have carried out a flux-limited IRS spectroscopic survey of some
100 disks down to the young brown dwarf limit. In addition, complementary
optical spectroscopy, millimeter emission and X-ray surveys have been done.
The majority of the disks show silicate emission, 8% have 30/13 micron flux
ratios consistent with cold disks with inner holes and 4% of the disks show PAH
emission. Comparison with models indicates that dust grains in the surface
layers have sizes of at least a few micron. No significant difference is found in
the distribution of silicate feature shapes and strengths between Serpens and
other well-studied large samples of disks such as that of Taurus. The remarkably
similar distribution in samples with different median ages imply that the dust
population in the disk surface results from an equilibrium between dust growth
and destructive collisional processes that is maintained over a few million years,
irrespective of environment.
2.3.14 Pebbles in Disks
Grains in disks around young stars are thought to grow from interstellar
submicron sizes to planetesimals, up to kilometres in size, over the course of
several Myr. The largest grains that can be detected have sizes of pebbles, and
can be best observed at centimeter wavelengths. However, other emission
mechanisms can contribute, most notably free-free emission from stellar winds
and chromospheric activity. Lommen, Wright (ADFA, Australia), Maddison
(Swinburne Univ., Melbourne, Australia) and collaborators used the Australia
Telescope Compact Array to determine the mechanisms of centimeter emission
for several T Tauri stars through monitoring over several years. Some disks have
confirmed grain growth up to at least millimeter sizes, whereas one source
shows variable emission at the longest wavelengths indicative of non-thermal
emission. A larger sample has subsequently been surveyed with ATCA and
SMA to search for correlations between the submillimeter spectral slope,
characteristic of grain growth across the disk midplane, and the 10 micron
feature, indicative of growth in the surface layers in the inner disk.

2.4 STAR FORMATION
2.4 Star Formation
2.4.1 Zonal Flows in Accretion Disks
Young stars and supermassive black holes are fed by accreting gas from an
orbiting disc, an accretion disk. Accretion is facilitated by the turbulent mass of
the gas. A path to make accretion disks turbulent is through the so-called
magnetorotational instability, which renders any Keplerian flow with an
appropriately strenghted magnetic field unstable. Accretion disk turbulence is
often studied in a corotating reference frame representing a small region in the
disk. However, such an approach neglects potentially important dynamics at
scales larger than the simulation box. Johansen, Youdin (CITA, Canada), Klahr
(MPIA, Heidelberg, Germany) developed a new numerical method that allows
the study of MHD turbulence in very large simulation domains. They found that
the turbulence has significant structure at large scales. The most striking feature
of their simulations was large scale "zonal flows", i.e. regions of faster or slower
rotation similar to the banded cloud structure on the giant planet Jupiter. Such
zonal flows can have important effects on planet formation, since pebbles and
rocks are trapped between regions of slower and faster rotation.
Figure 8. Zonal flows.
2.4.2 The Spitzer c2d Legacy: Statistics
The Spitzer c2d legacy team, led by Evans (Univ. Texas, USA), and including
van Dishoeck, van Kempen and Merin, performed a statistical analysis of the
more than 1000 YSOs found in the five star-forming clouds mapped by c2d.
2.4 STAR FORMATION
23
Current star-formation efficiencies are found to range from 3% to 6%, overall
from 15% to 30%. The star-formation surface density is more than an order of
magnitude larger than would be predicted from the Kennicutt relation used in
extragalactic studies, reflecting the fact that those relations apply to larger scales
where more diffuse matter is included in the gas surface density. The derived
lifetime for the embedded Class I phase is 0.44 Myr, considerably longer than
some estimates. Similarly, the lifetime for the Class 0 SED class, 0.1 Myr, with
the notable exception of the Ophiuchus cloud, is longer than early estimates. The
great majority (90%) of young stars lie within loose clusters with at least 35
members and a stellar density of 1 M_sun pc-3. The data confirm and aggravate
the "luminosity problem" for protostars. At a given Tbol, the values for Lbol are
less than predicted by standard infall models and scatter over several orders of
magnitude. These results strongly suggest that accretion is time variable, with
prolonged periods of very low accretion.
2.4.3 Mapping Molecular Gas in Stellar Nurseries
Hogerheijde, together with a large team of researchers from the UK and Canada,
is executing a Legacy Survey on the James Clerk Maxwell Telescope (JCMT)
using the HARP receiver array. This 'spectral-line camera' has revolutionized the
capabilities of the JCMT to map out the distribution of molecular gas in the
Universe. Hogerheijde is one of the coordinators of the Gould Belt Survey,
aimed at mapping all nearby star-forming regions in emission of CO and its
isotopes 13CO and C18O. Papers describing the first results of this survey were
completed in 2009, presenting maps of the star forming clouds in Serpens,
Taurus, and Orion. These clouds showed a remarkable variety of morphologies
and kinematics, illustrating the diversity of star-forming environments in the
Solar vicinity. This ranges from isolated, mostly quiescent condensations in
Taurus, to the much more energetic regions of Serpens and Orion which are
criss-crossed by protostellar jets and show indication of large-scale cloud
collisions.
2.4.4 High Mass Star Formation
Torstensson and Van Langevelde continued their studies of methanol masers
associated with high mass star formation. Collaborating with van der Tak
(SRON, Groningen) and Vlemmings (Bonn Univ., Germany), they obtained
interesting results on the nearest high-mass star-forming region Cep A, which is
studied as the archetypical source in the sample. Analysis of HARP data taken
with the JCMT allowed the derivation of the rotation temperature and column
density of the thermal methanol gas. The methanol is clearly associated with the
24
2.4 STAR FORMATION
central source in this famous HII region and the derived temperature peaks at
the location of the maser. Excitation models show that radiative excitation is
limited to the very central region.
Figure 9. Thermal methanol in Cep A, from left to right the integrated flux, the velocity
field and the line width of the methanol (7 1 7 -- 6 1 6) E-type transition is shown. This
is the strongest unblended line in the JCMT HARP spectra.
The direction of the outflow is roughly consistent with the orientation of the
methanol masers on the much smaller scale observed with the European VLBI
Network. The methanol masers straddling the waist of Cep A probably outline a
large ring structure perpendicular to the outflow axis of the central source.
Remarkably, the velocity field does not show a rotation signature but seems to
be dominated by a small radial motion. Thus, the ring may outline an accretion
shock, where in-falling gas hits the accretion disk.
Figure 10. The magnetic field configuration around the young massive star Cepheus A
HW2 and the location of the methanol regions from which the 3-D structure was
inferred. The figure shows a magnetic field almost perfectly perpendicular to the disk
through which matter is transported onto the star.
2.4 STAR FORMATION
25
Vlemmings observed the same Cep A methanol masers with MERLIN to obtain
measurements of the magnetic field direction. Although the interpretation of
maser polarization can be quite complex, the measurements reveal a structured
large scale magnetic field perpendicular to the accretion disk in this high-mass
YSO. Field structure and strength reveal that magnetic fields can be the
dominant force in regulating the formation of high mass stars. This is an
important clue that the formation mechanism of high mass stars may resemble
that of less massive stars.
2.5 Stars and Interstellar Matter
2.5.1 Searching for the Siblings of the Sun
Bean (Leiden and Missouri State University), Portegies Zwart and Brown used
data from the Hipparcos Catalogue to conduct a preliminary search for stars that
were born in the same cluster as the Sun: the Sun's Siblings. They ran simple
simulations of a cluster dissolving during the Sun's lifetime as it orbits in the
potential of the Galaxy. The stars lost from the cluster in the simulation end up
along the cluster's orbit and their characteristics (space distribution and
kinematics) should identify candidate siblings of the Sun in the Hipparcos
Catalogue. Bean and coworkers made a further selection among the candidates
by looking for stars that photometrically appear to have the same age as the sun
and then examined these by looking up accurate age and metallicity estimates in
the Geneva-Copenhagen Survey catalogue. Somewhat as expected, no actual
siblings of the Sun were found but the study forms a good basis for future
searches with larger astrometric and photometric surveys such as will be
provided by the Gaia mission.
2.5.2 An Arc of Gas and Dust around the Young Star DoAr21
Hogerheijde, Panič, Merin, and Schouten obtained detailed images of the
circumstellar dust around the young star DoAr21. It had been suggested that
this star is surrounded by a disk, which has already cleared-out its inner region - a telltale sign of disk evolution and possible planet formation. However, the
VLT-SINFONI and VLT-VISIR images obtained by Hogerheijde et al. showed a
very different picture: instead of a disk, the molecular hydrogen and the warm
dust form an arc on just one side, at roughly 70-200 AU from the star. The most
likely explanation is that DoAr21 is not surrounded by a cleared-out disk, but
instead that it just happens to travel past a dense cloud condensation in the Rho
Ophiuchi cloud. DoAr21 is known to be bright in X-rays, and this radiation
26
2.5 STARS AND INTERSTELLAR MATTER
should heat the surface of the condensation to hundreds if not thousands of K,
sufficient to explain the observed emission. The observations illustrated the
power of VISIR and SINFONI to probe the environment of young stars.

2.5.3 The Misaligned DI Herculis System
Albrecht led a study using the Rossiter-McLaughlin effect which reveals the
spin-orbital alignment in two binary star systems, a technique also used for
transiting extrasolar planets. In a Nature publication, they revealed that in one
of these systems, DI Herc, the orbital plane and spin-axis are strongly
misaligned. This unexpected result solved the 20-year old mystery of the slow
apsidal motion of this binary star system.
2.5 STARS AND INTERSTELLAR MATTER
27
2.5.4 Evolved Stars: Planetary Nebula Progenitors?
Amiri, van Langevelde, and Vlemmings (Bonn Univ., Germany) studied the role
of magnetic fields in shaping the circumstellar envelope of evolved stars that are
Planetary Nebula (PNe) progenitors. MERLIN observations of the OH maser
region in the so-called water fountain source W43A revealed circular
polarization. Amiri and coworkers interpreted this as caused by the Zeeman
effect and found the strength to be consistent with previous determinations of
the magnetic field in the jet-like water maser emission [see Figure].
Using Effelsberg 100 m telescope, the same team discovered another 22 GHz
water maser in the supposedly dead OH/IR star, IRAS18455+0448 for which the
sudden disappearance of the OH 1612 MHz line had been reported previously.
Such a dying OH/IR star should not possess a water maser. An interesting
possibility is that the new masing spots originate further out in the circumstellar
envelope, making this the youngest proto-PNe ever detected.

positions are with respect to the reference feature. H2O features are indicated by filled
circles and OH components are shown as triangles. Red and blue show the redshifted
and blueshifted features.

2.6 STRUCTURE OF THE MILKY WAY
2.6 Structure of the Milky Way
2.6.1 The Galactic Magnetic Field
Nota and Katgert studied the large-scale magnetic field in the Galactic plane in
the fourth Galactic quadrant. They used published rotation measures of pulsars
and extragalactic sources. They made a special effort to identify those objects for
which the distribution of free electrons between observer and source is probably
far from uniform. Structure in the distribution of free electrons biases the
estimate of the strength of the magnetic field from rotation measures, especially
if the field reverses direction somewhere along the line of sight or has structure
on small scales.
The strength of the large-scale field was estimated by comparing the acceptable
data to model predictions. It appears that the large-scale field most likely
follows the spiral arms. For a large range of assumed arm properties (such as
pitch angle and arm-width), the large-scale field shows two robust reversals;
from Norma arm (counter-clockwise) to Norma-Crux interarm region
(clockwise), and from Norma-Crux interarm region to Crux arm (CCW). The
field strengths are typically a few μGauss. At the same time, Nota and Katgert
found evidence for a small-scale field that is a factor of two to three stronger
than the large-scale field.
2.6.2 Bulge Dynamics: Studing the Closest Galactic Bar
Soto, Kuijken, and Rich (UCLA, USA) constructed a model of the stellar
kinematics towards the bar in the Milky Way bulge. They based the model on
new measurements of proper motions and radial velocities from HST and the
ESO-VLT, respectively. The VLT observations used an integral field unit to take
spectra of very crowded star fields in the bulge, from which stellar spectra were
then extracted using the precise position information measured on the HST
images. Repeat HST images separated by 3-5 years allowed accurate proper
motions (equivalent to 30km/s accuracy at the distance of the bulge) to be
measured. A separate analysis of a data set of K giants revealed a significant
vertex deviation in the metal-rich stars which is a clear signature of bar-like
kinematics. In their master thesis project, Zeballos and Astraatmadja derived
proper motions from HST data in three new fields, at galactic longitudes
between 5 and 10 degrees.

2.6.3. Mass Function of the Arches Cluster
The Arches cluster is one of only a handful of young and massive starburst
clusters in the Milky Way. Located at the Galactic center, this cluster is a unique
object for studying star formation and early cluster dynamics. Harfst and
Portegies Zwart constructed an N-body counterpart of the Arches cluster by
systematically comparing a large number of simulation results with
observations. The observational data were provided by Stolte (Cologne
University, Germany). The results showed that the flattened mass function
observed today is the result of the dynamical evolution of the cluster combined
with a selection effect. The Arches cluster is consistent with a standard Salpeter
initial mass function and not, as was considered in earlier studies, an counterexample to the universality of the initial mass function.

2.6.4 The Central Supermassive Black Hole
Levin, PhD students and international collaborators continued to work on issues
related to the supermassive black hole in the Galactic Center, and to
gravitational-wave detection.
Madigan, Levin, and Hopman identified a new secular instability in eccentric
stellar disks around supermassive black holes. They showed that a combination
of coherent torques and retrograde precession of the stellar orbits amplifies
deviations of individual orbital eccentricities from the average, and thus drives
all eccentricities away from their initial value. This physical process is relevant
for the Galactic center, where massive stars are likely to form in eccentric disks
around the SgrA* black hole. They showed that the dynamical evolution of such
a disk results in several of its stars acquiring high (e > 0.99) orbital eccentricities.
30
2.6 STRUCTURE OF THE MILKY WAY
Binary stars on such highly eccentric orbits would get tidally disrupted by the
SgrA* black hole, possibly producing both the S-stars, a cluster of young stars on
random orbits near the black hole, and hyper-velocity stars in the Galactic halo.
Levin, working with Genzel's group at MPE (Munich, Germany) has also
obtained new results on the geometry of the Galactic-Center stellar disks. This
work has shown that the clockwise disc is strongly warped and the
counterclockwise disc is dissolving.
2.7 Nearby Galaxies
2.7.1 Magellanic Clouds
To understand the impact of low metallicities on giant molecular cloud (MC)
structure, Israel as part of an international team working on Spitzer Space
Observatory data compared far-infrared dust and millimeter CO emission, and
dynamics in the star-forming complex N83 in the Small Magellanic Cloud wing.
Dust emission probes the total gas column independent of molecular line
emission and traces shielding from photo-dissociating radiation. They resolved
the relative structures of H2, dust, and CO within this a giant molecular cloud
complex, one of the first times such a measurement has been made in a lowmetallicity galaxy. The results indicated that the CO is photo-dissociated while
H2 self-shields in the outer parts of low-metallicity GMCs, implying that
dust/self shielding is the primary factor determining the distribution of CO
emission. The CO-to-H2 conversion factor averaged over the whole cloud is
very high, 20 to 55 times the local Galactic value. This factor also varies across
the complex, with the lowest values near the CO peaks. The bright CO emission
is occurs along line-of-sight with high extinction. A simple model in which CO
occurs in a smaller sphere nested inside a larger cloud roughly relates the H2
masses measured from CO kinematics and dust.
2.7.2 Star-Burst Modelling
Martinez Galarza, Groves, and Brandl developed a method to compare physical
models of star-burst spectral energy distributions with actual mid-infrared
spectra from the Spitzer Space Telescope. They accomplished their star-burst
modeling by implementing a reproducible least-square fitting method and
comparing the model spectra to the spatially averaged IRS spectral map of 30
Doradus, which is a very well-studied giant HII region complex in the Large
Magellanic Cloud. This approach can accurately constrain the relevant physical
parameters of the star formation activity in 30 Doradus in a comprehensive
2.7 NEARBY GALAXIES
31
manner, including the mass of the central cluster, the contribution of UCHII
regions, and the contribution of PDR material to the total luminosity and
compactness.
2.7.3 Molecular Gas in Late-Type Spiral Galaxies
Israel completed studies of molecular gas in the centers of the nearby star-burst
galaxies NGC 278, NGC 660, NGC 3628, NGC 4631, and NGC 4666. The bright
CO emission required modeling with at least two distinct gas components,
although the physical condition differ from galaxy to galaxy. Relatively tenuous
(less than a 1000 per cc) and warm (~125 K) gas occurs in all galaxies and is
mixed with cooler (~20 K) and denser (~6000 per cc) gas. Molecular gas masses
within radii of 0.6 to 1.5 kpc are about 100 million solar masses, i.e. no more than
a few per cent of the dynamical mass in the same region. In all galaxy centers
there is less H2 than CO intensities would suggest.
Figure 14. Major-axis-velocity diagrams of the merger/starburst NGC 660 (right) and
the starburst galaxy NGC4631 (left). NGC660 exhibits strong circumnuclear CO,
whereas the edge-on NGC4631 only shows a number of giant molecular cloud complexes
distributed throughout the disk.
As co-coordinator of the JCMT Nearby Galaxies Legacy Survey (NGLS) , Israel
and NGLS team members published a CO(3-2) study of four spiral galaxies in
the Virgo cluster ((NGC 4254, NGC4321, NGC 4569, and NGC 4579). The first
three have total molecular gas masses of about one billion solar masses and gas
depletion times of about 1.5 Gyr. NGC 4254 appears to have a smaller gas
depletion time (i.e. larger star formation rate) than the other, perhaps because it
is on its first passage through the Virgo Cluster. The interaction of NGC 4569
with the interacted medium appears to be directly affecting the dense starforming portion of the interstellar medium. NGC 4579, has weak CO(3-2)
emission although it is bright in the mid-infrared. Much of the central
luminosity in this galaxy may be due to the presence of a central AN.
The NGLS data of NGC 2403 were combined with Spitzer Space Telescope

infrared maps at wavelengths between 3 and 160 microns and VELA HI data.
In this very nearby Sabled galaxy, the dust surface density is a function of the
total hydrogen gas surface density and galactocentric radius. The gas-to-dust
ratio from ~100 in the nucleus to ~400 at 5.5 kpc radius. Its slope follows that of
the oxygen abundance, suggesting that metallicity strongly affects the gas-todust ratio within this galaxy. The CO(3-2) radial profile has an exponential scale
length identical to that of the (stellar continuum-subtracted) 8 micron PAH
emission. However, CO J=(3-2) and PAH 8 micron surface brightnesses are
uncorrelated on sub-kilo-parsec scales.
2.7.4 Infrared Study of the Antennae Galaxies (NGC 4038/39)
Brandl, Groves, van der Werf, Snijders, and Den Brok have studied the famous
Antennae galaxies NGC4038/39 with the Infrared Spectrograph on the Spitzer
Space Telescope. The spatially resolved spectra allowed a detailed study of the
luminosities, dust content, and emission properties of the super star-clusters in
the so-called overlap region. Molecular hydrogen was found to be rather
confined to the nucleus of NGC 4039, where shocks appear to be the dominant
excitation mechanism, and the southern part of the overlap region, where it
traces the most recent star-burst activity. The overall properties of the warm
molecular gas appear to be in good agreement with the findings in other starburst galaxies, which is in contrast to previously reported findings from ISO.
2.7.5 Atlas of High-Resolution Mid-Infrared Starburst Spectra
Together with collaborators at Cornell and Caltech, Brandl produced an atlas of
Spitzer/IRS high-resolution (R ~ 600) 10-37 micron spectra for 24 well-known
star-burst galaxies. The spectra are dominated by fine-structure lines (including
the high excitation [Ne V] line), molecular hydrogen lines, and emission bands
of polycyclic aromatic hydrocarbons (PAHs). The spectra also revealed weak
hydrocarbon features at 10.6, 13.5, 14.2 μm, and a previously unreported
emission feature at 10.75 μm. An unidentified absorption feature at 13.7 ?m is
detected in many of the starbursts. From the mid-IR fine-structure lines and the
atomic hydrogen (H 7-6) line, the metallicities for 14 objects were derived. The
spectra of all starburst galaxies were combined to create a high signal-to-noise
ratio template, which was subsequently made available to the community.
2.7.6 The SuperMassive Black Hole in Centaurus A
In one of the first Guaranteed Time observing runs with SINFONI on the VLT,
Van der Werf, De Zeeuw, Cappellari, Reunanen, Davies (MPE, Munich,
Germany), Neumayer, and Rix (MPIA, Heidelberg, Germany) observed the

optically obscured nucleus of the nearest radio galaxy Centaurus A. A nearby
star allowed adaptive optics corrections resulting in data with a K-band
resolution of 0.12 arcsec. The CO bandheads at 2.3 micron in this data set were
used to determine the central black hole mass from stellar kinematics. Due to
34
2.7 NEARBY GALAXIES
the very high signal-to-noise ratios, the shape of the stellar line-of-sight velocity
distribution was reliably extracted. Remarkably, the stars were found to
counter-rotate with respect to the gas. Using axisymmetric three-integral
models (see Figure), the team found the black hole mass to be 55+/-30 million
solar masses, in agreement with the earlier determination from the gas
kinematics. The result provided one of the cleanest gas versus stars comparisons
of MBH determination; it also brought Cen A into agreement with the general
MBH - sigma relation.
2.7.7 Using PN.S to Study Elliptical Galaxy Outskirts
The PN.S team (including Kuijken, Douglas, Arnaboldi, Capaccioli, Coccato,
Freeman, Gerhard, Merrifield, Napolitano, Noordermeer, Romanowsky) is in
the process of carrying out a study of elliptical galaxy halos. The PN.S is a
purpose-built narrow-band, two-arm slitless counter-dispersing spectrograph
that finds, and measures velocities of planetary nebulae (PNe) in external
galaxies from a single observation. The ongoing survey typically yields 100-200
PNe per galaxy, mostly beyond two effective radii from the center where
motions are dominated by the dark matter halo potential. The team has now
obtained good data sets for a dozen galaxies. Interestingly, a significant number
of galaxies exhibit a sharply declining velocity dispersion profile.
2.7.8 Nuclear Phenomena in Active Galaxies
De Vries, Snellen, Schilizzi, and Röttgering studied very young radio galaxies in
the expectation of shedding new light on the question why certain galaxies
become active and how the central activity influences the surrounding galaxy.
They showed that the expansion velocities of young radio sources depend on
their radio luminosity. Their analysis also indicated that the mortality rate of
radio-loud AGN is high during the earliest phase of their evolution.
Holt also continued working on radio galaxies at optical wavelengths, in
collaboration with Tadhunter (Sheffield, UK) and Morganti (Astron), among
others. They presented their results on the dominant ionization mechanisms in
the fast nuclear outflows in compact (young) radio galaxies.
Finally, Spoon (Cornell) and Holt reported the discovery of strongly blueshifted
mid-infrared neon emission lines in a sample of ULIRGs highlighting the
presence of outflows in these sources.
Jaffe, Oonk, and Hatch used the Hubble Space Telescope ACS to obtain evidence
for large-spread Far-Ultraviolet emission from cooling flow clusters. The source
2.7 NEARBY GALAXIES
35
of this emission is unknown; it may be young stars (unusual for elliptical
galaxies) or indirect emission from cosmic rays.
2.7.9 Nearby Clusters of Galaxies
Katgert and Biviano (Trieste, Italy ) calibrated the effects of projection (from 6-d
phase space to 2+1-d observation space) on the detection of kinematical and
dynamical substructure in the clusters of the ESO Nearby Abell Cluster Survey.
They used numerical simulations of clusters, in which all 6 phase-space
coordinates are available, so that the real kinematical and dynamical
substructure could be detected. These simulations were also projected into 2+1-d
pseudo-observations. Special attention was given to the question of a
meaningful cross-correlation between the properties of the substructure
observed in 6-d and in the 2+1-d projection.
2.8 Distant and High-Redshift Galaxies

observations of the merging cluster MACS J0717.5+3745 ($z=0.5$). The main central
radio emitting region is located at the interface between merging clusters. The
temperature of the X-ray gas in this interface region is relatively high, indicating that
shocks in the X-ray gas accelerate the radio emitting particles.
36
2.8 DISTANT AND HIGH REDSHIFT GALAXIES
2.8.1
Radio Cluster Haloes
Diffuse radio emission in clusters, often classified as radio "relics" or "haloes",
trace regions with shocks and turbulence resulting from cluster merger events.
Van Weeren, Röttgering, Brüggen (Bremen, Germany), and Cohen (NRL,
Washington, USA) have carried out low-frequency radio observations at 610
MHz with the Giant Meterwave Radio Telescope (GMRT) of diffuse ultra-steepspectrum sources and constructed the first sample of such sources associated
with clusters. They showed that smaller relics have steeper spectra and larger
relics are predominantly located in cluster outskirts while smaller relics
arecloser to cluster centers. They suspect that this is the consequence of larger
shock waves occurring mainly in lower-density regions and having larger Mach
numbers.
Combining radio and Chandra X-ray observations of the merging cluster MACS
J0717.5+3745 (z=0.5), Van Weeren, Röttgering, Brüggen, and Cohen (NRL,
Washington, USA) discovered the most powerful radio halo known. The
coincidence of steep-spectrum radio emission with high temperature X-ray gas
(see Fig. 1) constituted strong evidence that the radio emitting particles are
accelerated in a merger-related shock wave.
2.8.2 Radio Structure of Abell 2256
Abell 2256 is a massive cluster at a redshift of 0.0581. It is presently merging
with a smaller sub-structure. At radio wavelengths, the cluster reveals a very
complex morphology showing a bright peripheral radio relic, a radio halo,
several complex relatively compact filamentary sources and “head-tail” sources.
Van Weeren, Intema, Oonk, Röttgering and Clarke (Washington, USA)
complemented deep 325 MHz GMRT radio continuum observations with WSRT
115-165 MHz observations and optical WHT imaging (See Figure previous
page). They discovered three diffuse elongated radio sources about 1 Mpc from
the clustercenter with extents of 170, 140 and 240 kpc, respectively. Their
extremely steep radio spectra suggests them to be the result of adiabatic
compression of fossil radio plasma caused by merger shocks. They concluded,
from the timescales related to AGN activity, synchrotron losses, and the
presence of shocks, that most massive clusters should possess similar sources.
An exciting possibility is that such sources will determine the general
appearance of clusters in the low-frequency, high-\ resolution radio maps
produced by LOFAR or LWA.

2.8.3 Metallicities of Galaxies around Redshift of One
Brinchmann participated in two efforts to determine metallicities in galaxies at
redshifts between 0.5 and 1.3 from the Vimos Very Deep Survey. The effort led
by Lamareille (Toulouse, France) focused on the evolution of the massmetallicity relation with redshift using the same techniques as had previously
been applied to the Sloan Digital Sky Survey (SDSS). They found a modest
evolution in the relation out to z~0.7 and possibly some evidence for a change in
shape. The second effort, led by Pérez-Montero (Toulouse, France), focused on
calibrating a new metallicity indicator for use at redshifts out to z~1.3. This was
used to extend the study of the mass-metallicity relation to higher redshift, and
an evolution relative to the present-day Universe was found but no statistically
significant evolution was found between z~0.7 and z~1.
2.8.4 SDSS Galaxy Statistics
Brinchmann, mainly in collaboration with Christy Tremonti (U. Wisconsin,
USA), carried out a re-analysis of all SDSS DR7 spectra and derived physical
38
2.8 DISTANT AND HIGH REDSHIFT GALAXIES
parameters for all galaxies in the SDSS DR7, about 1 million. This dataset has
been provided on-line at http://www.mpa-garching.mpg.de/SDSS/DR7 and is
a reference dataset for galaxy properties in the SDSS. Brinchmann also
participated in an effort to study the effect of lopsidedness on the properties of
galaxies in the SDSS. The effort was led by Reichard (Johns Hopkins, Baltimore,
USA). They showed that lopsidedness in galaxies correlates with residuals in the
mass-metallicity relation and that powerful AGN tend to be hosted by lopsided
galaxies but that this is an incidental correlation. The physical correlation
appears to be that the delivery of cold gas to the central regions of galaxies,
triggering star formation and black hole growth, is aided by the process that
produce lopsidedness.
2.8.5 Blue-to-Red Ratio in Massive Clusters
Hoekstra, Willis, Urquhart (both Univ. of Victoria, Canada) and Pierre (CEA,
France) studied the fraction of blue galaxies (relative to galaxies on the red
sequence) for a combined sample of massive clusters (from the Canadian Cluster
Comparison Project led by Hoekstra) and low mass systems discovered by the
XMM-LSS survey. The results, although not fully conclusive, suggest that
environment may play an important role in setting the blue fractions of galaxy
clusters.
2.8.6 Galaxy Proto-Cluster Structure in the Early Universe
Miley, Hatch, Röttgering, Masschietto, Kuiper, and collaborators have been
using high-redshift radio galaxies (HzRGs) to probe galaxy and cluster
formation in the early Universe. The very massive luminous high-z radio
galaxies are the likely progenitors of cDs and Brightest Cluster Galaxies (BCGs).
Leiden studies focussed on (i) population and kinematic study of radio-selected
protoclusters from 2<z<4, (ii) studies of merging, AGN feedback and galaxy
downsizing in the massive cD progenitor hosts and (iii) preparation for a search
for z>6 HzRGs with LOFAR (potential probes of the Epoch of Reionization).
To unravel the history of protoclusters, it is essential to study galaxies of
different ages, masses and dust content. Lyman-alpha excess galaxies and
Lyman break-galaxies are dominated by young dust-free stellar populations,
while Balmer-break galaxies are dominated by older stars. The Leiden group has
shown that Lyman-alpha is a powerful tracer of the young star-bursting
population in z>2 protoclusters. They were allocated an ESO large project with
the tunable OSIRIS camera on the new Grantecan Telescope to make a Lymanalpha kinematic study of 19 HzRGs at 2<z<3.5. Highlights of these studies are
the population studies of Maschietto and collaborators and Kuiper on the
2.8 DISTANT AND HIGH REDSHIFT GALAXIES
39
protocluster MRC0316-257 at z=3.1, and Overzier and colleagues on
protoclusters at z>4.
Maschietto et al selected 13 candidate [OIII] emitters in a 1 Mpc2 region around
the z=3.1 radio galaxy, and followed up by spectroscopic observations. Three
[OIII] emitters have velocities within a few hundred km/s of each other, but
blue-shifted by about 2100 km/s from both the radio galaxy and the protocluster
Lyman-alpha emitters previously detected by Venemans et al. These results
indicate that the radio-selected protocluster is forming at the centre of a larger
superstructure with a size of 60 co-moving Mpc.
Kuiper and colleagues took this a step further and analyzed in detail four
distinct populations within this z>3.1 protocluster: the young stellar populations
pinpointed by Lyman alpha emitters and Balmer break candidates and the older
populations observed as [OIII] emitters and Balmer break candidates. They
found a radial spatial segregation within the protocluster. The galaxies with the
highest masses and star formation rates are located losest to the radio galaxy.
Thus, the protocluster environment already influences galaxy evolution at z~3.
2.8.7 The Spiderweb Galaxy
Miley and his collaborators have shown that HzRGs have many of the
properties expected from progenitor cD galaxies - clumpy optical morphologies,
spectra indicative of extreme star formation and large stellar masses. The best
studied example is the spectacular Spiderweb Galaxy at z=2.2, with a mass of
about 1012 solar masses, among the largest known. The galaxy is surrounded by
a giant (200 kpc) Lyman-alpha halo and embedded in dense hot ionized gas
with an ordered magnetic field. It is associated with a 3 Mpc-sized structure of
galaxies, of derived mass in excess of 2x1014 solar masses, a presumed
antecedent of a local rich cluster. HST studies by Hatch et al revealed
information about merging, downsizing, AGN feedback and intergalactic star
formation. For the Spiderweb Galaxy comparison of the UV luminosity (young
stars) with the IR luminosity (old stars) implied that most of the mass had
already assembled by z~2.2, consistent with downsizing scenarios. Intriguingly,
Hatch and colleagues showed that downsizing may also be occurring within the
Spiderweb itself. Although the less massive satellite galaxies contain only 30% of
the total mass, they are responsible for about 75% of the star formation.

on the composite ACS image. The gaseous nebula is extended by ~200 kpc and
comparable in size with the largest cD galaxies in the local Universe.
Right. A H-band HST/NICMOS image at ~500A rest-frame. Red circles indicate red
galaxies with little UV continuum. Note differences between the ACS image (young
population) and the NICMOS image (old population). Spectral comparisons and IFU
spectroscopy are being used to disentangle the history of star formation and structure
assembly.
Hatch and collaborators also found that about 40% of the UV light from the
Spiderweb is in a diffuse intergalactic component, probably produced by
intergalactic star formation at rates of 60 solar masses per year. This discovery
posed several questions. How ubiquitous is the extended light and what role
does it play in massive galaxy evolution? Are extended stars produced by gas
that has been stripped from the satellite galaxies?

Spiderweb Galaxy according to the decomposition shown at the top lefl. The first SED is
that of the central massive radio galaxy (Galaxy 1) and the other SEDs are those of 18
satellite galaxies. The derived mass of the Spiderweb is ~10M, of which 70% is in the
central object, whereas 75% of the star formation appears to occur in the less massive
satellite galaxies. These data are presently being complemented by IFU spectroscopy.

2.8.8 Faint Submillimeter Galaxies
Van der Werf, Knudsen (MPIfR, Bonn, Germany) and Kneib (LAS, Marseilles,
France) studied the molecular (CO) properties of intrinsically faint
Submillimeter Galaxies, gravitationally lensed by the massive cluster A2218.
With the Plateau de Bure Interferometer they detected CO J=2-1 and J=4-3
emission from two SMGs at redshifts z=1.034 and z=3.187. They used the
measurements to estimate molecular gas masses and star formation efficiencies,
the results being consistent with the local L(FIR)-L(CO) relation. One of the
objects had the lowest far-infrared luminosity of all SMGs with a known redshift
and is one of the few high-redshift LIRGs whose properties can be estimated
prior to ALMA.
2.8.9 Massive starburst galaxies at redshift 2
Van der Werf also collaborated with a team led by Huang (CfA, Boston, USA) in
a study of infrared colour-selected galaxies. The selection criteria efficiently
42
2.8 DISTANT AND HIGH REDSHIFT GALAXIES
isolated massive star-forming galaxies at a redshift of approximately 2. The
fractional luminosity in Polycyclic Aromatic Hydrocarbon (PAH) features for
the new sample is the highest ever seen, about three times higher than in local
starbursts. HST images show that most objects have very extended
morphologies in the rest-frame ultraviolet band. The resulting sample
constitutes the first starburst-dominated ULIRG sample at high redshift with
total infrared luminosity measured directly from FIR and millimeter
photometry, and as such gives us the first accurate view of broadband spectral
energy distributions for starburst galaxies at extremely high luminosity and at
all wavelengths.
2.8.10 Lyman-BreakGalaxies at 3<z<5
Hildebrandt and coworkers selected the largest samples of high-redshift (3<z<5)
galaxies to date, using Lyman-break imaging data from the Canada-FranceHawaii-Telescope Legacy Survey. They measured the clustering of the ~80 000
star-forming galaxies to unprecedented accuracy which yielded estimates of the
masses of the dark matter halos hosting those Lyman-break galaxies (LBGs).
They used the same sample to establish a new observational technique of using
weak gravitational lensing to study cosmology. They succeeded in detecting the
cosmic magnification effect in the LBGs, the first time this was done with normal
galaxies. This effect introduces characteristic angular cross-correlations between
galaxies at low and at high redshift due to weak lensing by the foreground
galaxies. Hildebrandt and coworkers showed that the signal scales with
magnitude and redshift as expected from lensing theory (see Fig. 1).
2.8.11 Distant Galaxies and the Red Sequence
Damen, Franx, and collaborators found that the specific star formation rates of
massive galaxies out to z=3 increases rapidly with redshift (roughly like (1+z)5).
The increase is similar for all masses, but galaxies with higher masses have
lower average specific star formation rates. The observed high specific star
formation rates lie well above the levels that can be reproduced by the current
models for galaxy formation that generally predict specific star formation rates
on the order of 1/t(hubble).
Williams, Quadri, Franx, and collaborators used the Ultra Deep Near-IR Survey
and found that galaxies with little star formation can be identified in a red
sequence out to z=2 by combining the near-IR photometry with optical and 3-5
micron photometry from the Spitzer Space Telescope. In the rest-frame U-V, V-J
color-color diagram, the star-forming galaxies lie in an area different from the
“quiescent galaxies”. This new diagnostic is confirmed by using the mid-IR
2.8 DISTANT AND HIGH REDSHIFT GALAXIES
43
emission at 24 micron, which shows strong emission from star-forming galaxies
and none from the quiescent galaxies.
Holden (UC Santa Cruz, USA), Franx, and collaborators showed that early-type
galaxies in high-z clusters have the same ellipticity distribution as early-type
galaxies in clusters at low-z. This suggests strongly that the average bulge-todisk ratio is rather similar, and does not evolve. It also indicates that earlier
efforts in trying to distinguish ellipticals and S0s are not effective. Taylor, Franx,
and collaborators showed that red galaxies can be identified out to a redshift of
two. Although photometric errors hamper the definition of red sequence
galaxies at z=2, it is likely that a significant fraction of massive galaxies were
‘’red” at that redshift.
2.8.12. Evolving Galaxies in the Distant Universe
Kriek (Princeton Univ., USA), Franx, and collaborators obtained a very deep
spectrum of a compact, massive galaxy at z=2.1. The spectrum shows clear
absorption lines, indicating a 2 Gyr old galaxy. The galaxy must have formed at
significantly higher redshift. In addition, the galaxy had weak liner-like
emission lines, indicating the presence of an AGN. Van Dokkum (Yale Univ.
USA), Kriek, and Franx measured the velocity dispersion to be 510 +- 100 km/s.
The error on this measurement is large but the galaxy clearly is truely massive,
and lies far from the local mass-size or velocity dispersion – size relation.
Kriek, Franx, and collaborators presented high resolution imaging of z=2.3
galaxies with previously obtained rest-frame optical spectroscopy. There is a
clear separation of galaxies into star-forming, large systems and compact
quiescent systems showing that the equivalent of the Hubble Sequence is
present at that redshift. Brammer (Yale Univ., USA), Franx, and collaborators
used a new, medium band near-IR survey to derive very accurate photometric
redshifts and rest-frame colors. The survey shows a distinct red sequence for the
galaxies without star formation. These galaxies can be selected based on their
spectral energy distributions, or based on the absence of mid-IR emission as
measured by the Spitzer Space Telescope.
Bouwens (Univ of Santa Cruz, USA), Franx, and collaborators analyzed the
properties of high redshift galaxies and found that high-z galaxies become bluer
at higher redshift (from z=3 to z=7), and at lower intrinsic magnitude. The
highest redshift galaxies are extremely blue, and hard to model. Muzzin (Yale
Univ., USA), Franx, and collaborators found consistently high masses,
independent of model assumptions used, for the very compact galaxies at z=2.3.
44
2.8 DISTANT AND HIGH REDSHIFT GALAXIES
Hence it is very hard to explain their small sizes by postulating that their masses
are overestimated by a large factor.
Marchesini (Yale Univ., USA), Franx, and collaborators studied the evolution of
the stellar mass function from z=3.5 to low-z. They specifically studied the
uncertainties due to random and systematic effects, including the effect of
metallicity, extinction law, stellar population synthesis model, and initial mass
function. They show that these uncertainties dominate all other uncertainties.
2.8.13 The LABOCA ECDFS Submillimeter Survey (LESS)
Van der Werf participated in a new large-area submillimeter survey that was
carried out with the LABOCA 870 micron bolometer camera at the APEX
telescope, by a team led by Smail (Durham, UK), Weiss (MPIfR, Bonn, Germany)
and Walter (MPIA, Heidelberg, Germany ). The LABOCA ECDFS Submillimetre
Survey (LESS) covers the full 30' x 30' field size of the Extended Chandra Deep
Field South and is thus the largest contiguous deep submillimeter survey
undertaken to date. In total 126 SMGs were detected with a significance level
above 3.7 sigma. The field is sufficiently large that it can be shown that the shape
of the source counts is not uniform across the field. Instead, it steepens in
regions with low SMG density. This survey also allowed an investigation of the
clustering of SMGs in the ECDFS by means of a two-point correlation function,
providing evidence for strong clustering on angular scales <1' with a
significance of 3.4 sigma. Another result from this survey was the discovery of
the most distant SMG known today with a spectroscopic redshift (z=4.76).
2.8.14 Weak Lensing in the COSMOS Field
Schrabback, Hoekstra, Kuijken, Hildebrandt, Semboloni, and Velander
completed a comprehensive analysis of the large-scale mass distribution in the
HST map of the COSMOS field, together with collaborators in the EU-funded
DUEL network. A key development was the inclusion of accurate photometric
redshifts for large numbers of galaxies, allowing a measurement of the evolution
of the growth of large-scale structure and a 3-D tomographic lensing analysis.
For the first time, they could show that the weak shear of distant galaxies scales
with redshift as expected in the standard LambdaCDM model. This established
the combination of weak lensing and photometric redshifts as a cosmological
probe. The results of the 1.6-square degree survey confirmed the accelerated
expansion of the universe, and demonstrated the potential of all-sky space-based
weak lensing and photometric redshift surveys for precise measurements of the
properties of the dark energy.

cosmic microwave background. Right: Constraints on the density of matter Omegam and

acceleration, providing further support for the presence of dark (or vacuum) energy.
2.8.15 Magnification Mapping of the Large-Scale Structure
From the 4 square-degree CFHTLS-deep survey, Hildebrandt and collaborators
(including members of the Leiden lensing group led by Kuijken and Hoekstra)
compiled a large sample of high redshift Lyman-break galaxies. They
convincingly demonstrated that these sources are correlated with foreground
galaxies, due to the magnifying action of gravitational lensing. Though the effect
is statistically less powerful than weak shear measurements, it can be applied to
distant unresolved galaxies and therefore provides a complementary way of
measuring the matter distribution from gravitational lensing, particularly for
sources at high redshift. The study also served as an excellent qualification of
photometric redshifts, which are a crucial component of any future projects to
probe the cosmological model using gravitational lensing.
2.8.16 Radio Haloes as Tracers of Cosmological Structure
Radio haloes provide one of the most important pieces of evidence for nonthermal components in large scale structure. Statistics of their properties can be
46
2.8 DISTANT AND HIGH REDSHIFT GALAXIES
used to discriminate among various models for their origin. Cassano, Brunetti
(Bologna, Italy), Röttgering, and Brüggen (Bremen, Germany) carried out Monte
Carlo simulations to model the formation and evolution of radio haloes in a
cosmological framework. First, they computed the fraction of galaxy clusters
that show radio halos and derived the luminosity function of radio halos. Then,
they established differential and integrated number count distributions of radio
haloes at low radio frequencies with the goal of exploring the potential of the
upcoming LOFAR surveys. By restricting themselves to clusters at redshifts
z<0.6, they found that the planned LOFAR all sky survey at 120 MHz may
detect about 350 giant radio haloes.

high eccentricity, the double-discontinuity layer beteen the stars is pierced by both stars

2.9.1 Double-Winds in Eta Carinae
Icke continued his exploration of the hydrodynamic behaviour of double-wind
massive binaries, in preparation for his NWO project on the extreme binary star
Eta Carinae. This system is one of the most complex and fascinating objects in

our Galaxy: a supermassive interacting binary at the centre of a bipolar nebula
expanding at about 500 km/s.
The investigation aims at finding the
mechanisms behind Eta Car's appearance and behaviour. Icke has already
extensively explored the general types of flow pattern expected.
2.9.2. Pulsar Timing and Gravitational waves
Van Haasteren and Levin continued their work on Pulsar Timing Array (PTA)
data analysis. They developed, together with McDonald and Lu (CITA, Toronto,
Canada), a Bayesian analysis method to detect the stochastic gravitational-wave
background, thought to be emitted by an ensemble of supermassive black-hole
binaries in galactic centers. Application of the analysis method to data of the
European Pulsar Timing Array has led to the determination of a gravitationalwave background upper limit. van Haasteren and Levin also showed that the
general relativistic effect of gravitational wave memory can be used to detect
physical mergers of supermassive black holes in distant galactic nuclei.
2.9.3 AMUSE: Astrophysics Multipurpose Software Environment
The core development team of AMUSE (Van Elteren, Pelupessy, Marosvolgyi
and de Vries) released the first version of the AMUSE package for
computational astrophysics. The initial release consisted of the basic framework
and initial implementations of codes in the gravitational dynamics and stellar
evolution domains. Later releases will also include support for hydrodynamics
and radiative transport.
MUSE is a software framework for combining existing computational tools for
different astrophysical domains into a single multiphysics, multiscale
application and facilitates the coupling of existing codes written in different
languages by providing inter-language tools and by specifying an interface
between each module and the framework. This approach allows scientists to use
combinations of codes to solve highly-coupled problems without the need to
write new codes for other domains or significantly alter their existing codes.
MUSE currently incorporates the domains of stellar dynamics, stellar evolution
and stellar hydrodynamics for studying generalized stellar systems. MUSE
treats multi-scale and multi-physics systems in which the time- and size-scales
are well separated. The current MUSE code base is publicly available as open
source at http://muse.li.
2.9.4 N-body simulations on Graphical Processing Units
Pelupessy has examined star formation and the evolution of the molecular gas
phase using computer simulations. He developed a novel method to include the
48
2.9 SIMULATIONS, MODELS, THEORY
multiscale physics inherent in these processes into galaxy-scaled simulations.
This new method reproduces fundamental relations between star formation, gas
surface densities and observed molecular gas fractions.
Gravitational direct N-body simulations can be performed using the commercial
NVIDIA GeForce 8800GTX Graphics Processing Unit (GPU). The force
evaluation of the N-body problem is implemented in CUDA using the GPU to
speed-up the calculations. Portegies Zwart and collaborators tested the
implantation on three different N-body codes, two direct N-body integration
codes, using the 4th order predictor-corrector Hermite integrator with block
time-steps, and one Barnes-Hut treecode, which uses a 2nd order leapfrog
integration scheme. The integration of the equations of motions for all codes
was implemented in C on the host computer.
For simulations involving more than 512 particles the GPU outperforms the
special purpose GRAPE-6Af, if some softening in the force calculation is
accepted. Without softening and for very small integration time steps the
GRAPE still outperforms the GPU. Portegies Zwart and co-workers concluded
that modern GPUs offer an attractive alternative to GRAPE-6Af special purpose
hardware.
2.9.5 Shock-Processing of PAHs
Micelotta, Tielens, and Jones (IAS, Paris, France) have studied the processing of
large Polycyclic Aromatic Hydrocarbon (PAH) molecules in interstellar shocks
and in the hot gas associated with supernova remnants. Their analysis used a
detailed model of the physical interaction of energetic electrons and ions with
large molecules and established PAH molecule destruction timescales of 100
million years in the interstellar medium. The widespread association of PAH
emission with hot, X-ray emitting gas reveals the importance of neutral material
entrainment by explosions and fast stellar winds. PAHs act thus as colorful dye
markers for such phenomena.
Tielens collaborated with Boersma (RU Groningen), Allamandola, Bauschlicher
(both NASA Ames Research Center, CA, USA), and Peeters (UNO) in a study of
the emission characteristics of large PAH molecules at far-infrared wavelengths,
using the NASA Ames data base of PAH infrared spectra. The results showed
that the so-called drum head modes of PAHs are very characteristic of molecular
size rather than molecular structure. Observations with the PACS instrument on
board the Herschel Space Observatory are expected to provide key information
on the population of large PAH molecules in space.

Molecular sizes are in the range (16 to 130 C-atoms) that is thought to dominate the
interstellar PAH family. The dashed line indicates the frequencies expected for an
unclamped drum with a rigidity characteristic of PAHs.
2.9.6. Diagnosing the Excitation of Extragalactic Ionized Gas.
Groves created a new emission line tool for diagnosing the excitation
mechanism of ionized gas in galaxies. His code, named ITERA (IDL Tool for
Emission-line Ratio Analysis) enables users to compare observed emission line
ratios with existing libraries of photoionization and shock models, involving
supernova, AGN and starforming regions. ITERA was put publicly on-line at
http://www.brentgroves.net/itera.html. In addition, his on-going work with
Jonsson (CfA, Harvard, USA), included the implementation of his star formation
region SEDs in a pre-existing 3-D radiative transfer code (SUNRISE). The code
can be applied to hydrodynamical simulations of galaxies creating full UV-to-IR
spectra of both quiescent and merging galaxies viewed at any inclination, on
either global or kiloparsec scales.

2.9.7. SIMPLEX and Cosmic reionization
Paardekooper developed a transport scheme for the SimpleX radiative transfer
method that ensures correct photon transport in the low optical depth regime.
This new transport scheme shows the results of standard test problems to
correspond much better with the analytical solution (if available) and the results
of other, more conventional radiative transfer methods. At the same time, the
advantages of SimpleX remain, such as the high computational speed and the
independence on the number of sources thereof. Paardekooper then used
SimpleX to study the escape fractions of ionizing photons from high-redshift
dwarf galaxies, which is an important parameter in models of cosmic
reionisation. By post-processing dwarf galaxy models with realistic supernova
and stellar wind feedback and star formation, Paardekooper and Pelupessy
showed that high-z dwarf galaxies played an important role in early stages of
cosmic reionisation.

Kruip devised a method to translate density/opacity fields from
hydrodynamical simulation to an unstructured Delaunay grid optimized for the
SimpleX radiative transfer method. Such a scheme paves the way to the
coupling of SimpleX to hydrocodes. He also implemented multi-frequency
support in SimpleX and substantially extended the physics module of the
method.
2.9.8. Photo-ionization and Cooling Rates of Astrophysical Plasmas
Wiersma, Schaye, and Smith (Univ. Colorado, USA) investigated the effects of
photo-ionization of heavy elements by the meta-galactic ionizing background
and those of variations in relative abundances on the cooling rates of optically
thin gas in ionization equilibrium. They found that photo-ionization by the
background radiation strongly reduces the net cooling rates at gas densities and
temperatures typical of the shock-heated intergalactic medium and of protogalaxies. They concluded that both photo-ionization by the ionizing background
and heavy elements need to be taken into account in order for cooling rates to be
correct within an order of magnitude, and that more accurate rates require
departures of the relative abundances from solar to be taken into account.
2.9.9. Keeping the Universe Ionised
Pawlik, Schaye, and Van Scherpenzeel conducted a suite of cosmological
simulations to calculate the clumping factor of the IGM at redshifts z >>= 6. The
critical star formation rate density required to keep the intergalactic hydrogen
ionised depends crucially on the average rate of recombinations in the
52
2.9 SIMULATIONS, MODELS, THEORY
intergalactic medium (IGM), which is proportional to this clumping factor.
They found that photo-ionization heating by the ultraviolet background
strongly reduced the clumping factor as the increased pressure support
smoothed out small-scale density fluctuations, making it easier to keep the
universe ionised. They also found that the observed population of star-forming
galaxies at z ~ 6 is sufficient to keep the IGM ionized if it was reheated at
redshifts earlier than z = 9 and the fraction of ionizing photons escaping starforming regions to ionise the IGM exceeds 0.2.
Figure 25. The effect of photo-heating on the gas density distribution of the intergalactic
medium at redshift z=6. The figure shows the gas density contrast in a slice of comoving
3.125 Mpc/h on a side through a hydrodynamical simulation at redshift z = 6. The
simulation on the left did not include reionization, while for the one shown on the right
the ionizing background radiation was turned on at z = 9. The reheating associated with
reionization strongly suppresses the clumpiness of the intergalactic medium. The
associated reduction of the recombination rate strongly reduces the star formation rate
required to keep the universe ionized.
2.9 SIMULATIONS, MODELS, THEORY
53
Pawlik and Schaye investigated the interplay between photo-heating associated
with cosmic reionization and kinetic feedback from core-collapse supernovae in
a set of cosmological simulations. They showed that photo-heating and
supernova feedback mutually amplify each other's ability to suppress the highredshift cosmic star formation rate.
Figure 26. The relation between black hole mass and dark matter halo mass. The grey
pixels show the simulation predictions. The solid, red line withj a slope of 1.55 marks
the observational determination of the MBH vs MHalo relation. The dotted, red lines show
the observational 1-sigma errors. The slope and its scatter suggest that halo binding
energy rather than halo mass determines black hole masses.
2.9.10 SuperMassive Black Holes and Feedback from AGNs
Booth and Schaye presented a method that self-consistently tracks the growth of
supermassive black holes (BHs) and the feedback from active galactic nuclei
(AGN) in cosmological, hydrodynamical simulations. Because cosmological
simulations at present lack both the resolution and the physics to model the
multiphase interstellar medium, they tend to strongly underestimate the BondiHoyle accretion rate. To allow low-mass BHs to grow, it is therefore necessary to
increase the predicted Bondi-Hoyle rates in star-forming gas by large factors.
Booth and Schaye found that the freedom introduced by the need to increase the
predicted accretion rates by hand, is the most significant source of uncertainty in
54
2.9 SIMULATIONS, MODELS, THEORY
the model. Their simulations demonstrated that supermassive BHs are able to
regulate their growth by releasing a fixed amount of energy for a given halo
mass, independent of the assumed efficiency of AGN feedback, which sets the
normalization of the BH scaling relations. They further showed that, regardless
of whether BH seeds are initially placed above or below the BH scaling relations,
they grow on to the same scaling relations. Finally, they demonstrated that AGN
feedback efficiently suppresses star formation in high-mass galaxies.
2.9.11 Formation of High-Redshift SuperMassive Black Holes
Schleicher, Spaans and Glover examined the chemical conditions for black hole
formation in massive primordial galaxies at z>10. They focussed on the effects
of Lyman-alpha trapping and photo-dissociating radiation from nearby galaxies.
They found that the combination of these effects can keep the primordial gas at
temperatures larger than 5000 K during the collapse, which may give rise to
large accretion rates on the central clump. However, as the temperature slightly
decreases with density, fragmentation cannot be totally suppressed. The
formation of a central clump may thus be accompanied by a nuclear starburst.
2.9.12 Chemical Enrichment in Cosmological Simulations
Wiersma, Schaye, Theuns (Durham, UK), Dalla Vecchia, and Tornatore (Trieste,
Italy) presented an implementation of stellar evolution and chemical feedback
for smoothed particle hydrodynamics simulations. They considered the timed
release of individual elements by both massive (Type II supernovae and stellar
winds) and intermediate-mass stars (Type Ia supernovae and asymptotic giant
branch stars). A comparison of nucleosynthetic yields taken from the literature
indicated that relative abundance ratios may be reliable only to factors of two,
even for fixed initial mass functions. Abundances relative to iron were found to
be even less certain as Type Ia supernova rates are poorly known. Wiersma et
al. investigated, using several large simulations, the evolution of the distribution
of heavy elements and found them to be in reasonably good agreement with
observational constraints. In the local universe, most of the metals are locked up
in stars. The gaseous metals are distributed over a very wide range of densities
and temperatures. The shock-heated warm-hot intergalactic medium has a
relatively high metallicity of 0.1 solar that evolves only weakly. It is therefore an
important reservoir of metals. Any census aiming to account for most of the
metal mass will have to take a wide variety of objects and structures into
account.

2.9.13 How to Study X-Ray Dominated Regions with ALMA
Schleicher, Spaans and Klessen looked into the possibilities of detecting the
central X-ray-dominated regions (XDRs) of high-redshift quasars with ALMA.
They showed that the expected sensitivity and angular resolution of ALMA
should be sufficient to detect and at least marginally resolve such XDRs. The
XDRs can be distinguished from starbursts on the same spatial scales by using
the CO line transition ladder. Schleicher and colleagues estimated the expected
CO line fluxes, as well as various fine-structure lines, illustrating their
dependence on X-ray luminosity, cloud column density and gas volume density.
They compared their models to observations of local and high-redshift objects
such as NGC 1068, APM 08279 and SDSS J114816.64+525150.3. They found that
both a cold low-density component and a warm high-density component were
required to explain the observed line fluxes of the latter.

power spectrum of matter fluctuations on strongly non-linear regime and they
can provide competitive constraints on cosmological parameters. Semboloni has
recently completed the first three-point cosmic shear analysis using data from a
galaxy catalogue produced by Schrabback, who was able to estimate highly
accurate galaxy shapes in COSMOS images.
2.10 Instruments and facilities
2.10.1 The Low-Frequency Array (LOFAR)
LOFAR is a next-generation radio telescope that will observe in the frequency
range of 10 to 240 MHz, presently being built by a Dutch consortium led by
ASTRON. At the end of the year, hardware of 20 stations had been placed in the
fields and connected to the central processor.
Rollout of the LOFAR
international stations also made excellent progress with the Effelsberg station
coming fully on-line and the Tautenburg and Unterweilenbach stations only
awaiting HBA tiles. In parallel with the station rollout, deployment of the first
phase of LOFAR dedicated processing hardware was completed. This provided
10 TFLOPS of processing power and 2 PB of storage space. A first version of the
LOFAR imaging pipeline was installed on the new hardware and started to be
used to support commissioning activities.
The Leiden LOFAR survey team (Röttgering, Miley, Snellen, Mohan, Birzan,
Rafferty, van der Tol, Intema, van Weeren, and van Bemmel) concentrated on (i)
testing and commissioning of LOFAR data, (ii) building software for the source
extraction and characterization and for simulation of the LOFAR sky and (iii)
ionospheric calibration. Birzan, Rafferty and van Weeren were deeply involved
in taking and reducing first LOFAR data and testing the BSS reduction pipeline (
Figure below). While Birzan concentrated on reducing VLA data with BBS as a
test of the software system, Rafferty worked on comparing the various methods
to deal with Radio Frequency Interference. Mohan worked on his source
extraction pipeline. The methods are now sufficiently robust that they deliver
science quality source lists. Intema and Van der Tol designed and tested a
method to take out ionospheric disturbances from low-frequency radio data on
the basis of a 2-D ionospheric model. Extensive testing on VLA 74 MHz data
showed improvements of up to a factor of 2 in dynamic range over classical
methods.

observations were made with a 24 MHz bandwidth spread over a 30-75 MHz frequency
range. The full field of view is ~ 6 x 3 degrees of which only 20% is shown here.
In collaboration with the MeqTree team at ASTRON, Van Bemmel has
developed the SimCa module to simulate the impact of ionospheric turbulence
and waves on LOFAR observations. Under average ionospheric conditions,
coherence is lost below 15 MHz. This implies that observing at low frequencies
is only possible under excellent ionospheric conditions. Van Bemmel also tested
the LOFAR pipeline software (BBS) in simulations. This uncovered some
interesting and not yet understood behaviour in the package, demonstrating the
power of using simulated data for software testing.
Cohen (NRL, Washington, USA) and Röttgering used data from the nearly
complete 74 MHz VLS Survey of the entire sky visible to the VLA telescope in
Socorro, New Mexico to study the the impact of the ionosphere on lowfrequency radio observations. They obtained a detailed characterisation of the
dependence of the median differential refraction on source pair separation,
elevation, and time of day.
58
2.10 INSTRUMENTS AND FACILITIES
They found large, but geometrically predictable at elevation effects that can be
removed analytically with a 'thin-shell"'model of the ionosphere. They also
noted significantly greater ionospheric spatial variations during the day than at
night. The diurnal variations appeared to affect the larger angular scales to a
greater degree indicating that they are caused by disturbances on relatively
large scales (hundreds, rather than tens of kilometres).
2.10.2 ALLEGRO: the ALMA Regional Center Node in the Netherlands
The year 2009 has been pivotal in the construction of ALMA, the Atacama Large
Millimeter / Submillimeter Array. In Chile, aantenna assembly progressed
steadily, and the first three antennae arrived at the Llano de Chajnantor. All
receiver bands have seen first light on the sky, and three-element interferometry
was established by the end of the year. At Leiden Observatory, the ALMA
Regional Center node (Allegro, ALMA Local Expertise Group) led by
Hogerheijde took further shape with a grant for long-term funding from NWO,
and the hiring of Brinch as Allegro postdoc. In addition to contributions to
testing of the ALMA software, Allegro has focused on the use of the expandedSMA as a testbed for submillimeter interferometry and the use of the CHAMP+
receiver on APEX for exploring the submillimeter sky. CO line measurements of
a sample of AGB stars have been performed with this instrument, and analysed
to form a calibration set for ALMA.
2.10.3 The expanded Submillimeter Array (eSMA)
The eSMA combines the dishes of the SMA, JCMT and CSO on the summit of
Mauna Kea (Hawaii, USA) into a single facility, providing enhanced sensitivity
and spatial resolution owing to the increased collecting area at the longest
baselines. Until ALMA early science observing (2011), the eSMA will be the
facility capable of the highest angular resolution observations at 345 GHz. In
2009, development of the eSMA progressed toward making it a working
interferometer, involving Tilanus (JCMT), van Langevelde, Hogerheijde, and
Van Dishoeck, together with colleagues from SMA and CSO. Successful science
demonstration observations were obtained, followed by numerous tests of the
receivers and correlator to fully characterize the interferometer and its
sensitivities. The science demonstration observations included imaging of the
protostellar binary IRAS 16293-2422, resolving its component A into multiple
sources of emission of continuum and warm methanol. In contrast, its
component B, while clearly resolved by these high angular resolution data,
remains a single source, and exhibits remarkable absorption of the same
methanol lines.

2.10.4 VLTI: MIDI and Matisse
Jaffe continued his work on midInfrared interferometric observations of AGNs
with the VLTI instrument MIDI in collaboration with Raban and Röttgering, as
well as colleagues at MPIA Heidelberg and Bonn (Germany), and NRAO (USA).
Their most important result was a demonstration of the extreme irregularity of
the dust structures around the nearby Seyfert galaxy NGC~1068. These
irregularities are indirect but strong proof of the clumpy nature of the dust.
Jaffe is also the Dutch PI for the instrument MATISSE, which has been accepted
as a second generation VLTI instrument by ESO. The ESO council and the team
agreed on the GTO allocation to the consortium upon completion. The Cold
Optical Bench for MATISSE will be built in Dwingeloo. Jaffe is on the Science
Team and the Instrument team with special responsibility for real-time data
processing and polarization characterisation. MATISSE should be at Paranal,
Chile in 2014.

MUSE, the Multi Unit Spectroscopic Explorer is a second generation instrument
for the VLT, featuring Wide-Field, Adaptive Optics Assisted Integral Field
Spectroscopy. MUSE passed its final design review and is currently being
manufactured by a number of European companies. Integration will to start in
mid-2010. The MUSE consortium consists of 7 institutes and is lead by the

involved in the interface between MUSE and its Adaptive Optics system
(GALACSI), the preparations for scientific operation of MUSE--like the

ASSIST--the Adaptive Secondary Setup and Instrument STimulator is the test
system for the VLT Adaptive Optics Facility (AOF) and will allow for
verification of the operation of the various hardware and software systems for
the AOF without the need for--sometimes long--on-sky testing. ASSIST, as
currently being developed by Deep, Stuik and Wiegers has passed its Final
Design Review and is currently being manufactured. The main optical
components were well under way at the end of 2009 and the mechanical
components will be ordered in early 2010, in time for the integration of the main
components by the end of 2010.
2.10.6 KiDS: Studying Dark Matter with Light Rays
Kuijken continued his role as P.I. of the KiDS project, a large collaboration of
nine European institutes that will map 1500 square degrees of sky in good
seeing conditions with OmegaCAM on the VST in Paranal, in order to find
gravitational lenses. Weak gravitational lensing can be used to study the mass
distribution around galaxies and on larger scales. Unfortunately the telescope
construction has been long delayed, with start of operations considered likely
only in 2010 at the time of writing. Over 2009, preparations for KiDS continued
in the form of algorithm development for multi-colour photometry and for weak
lensing measurement. Members of the KiDS team were also involved in the
analysis of the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS),
currently the most powerful data set for weak lensing measurements. It
comprises 170 square degrees of sky imaged in five bands. The CFHTLS analysis
made it possible to identify and address various systematic effects that plague
the measurements.
2.10.7 E-ELT-METIS
Brandl, Stuik, Molster, Kendrew, van Dishoeck and van der Werf worked on the
conceptual study of METIS - the Mid-Infrared E-ELT Imager and Spectrograph.
With a mirror diameter of 42 meter, the European Extremely Large Telescope (EELT) project aims to provide European astronomers with the largest opticalinfrared telescope in the World. METIS is a combined imager and spectrometer,
working in the thermal/mid-infrared wavelength range from 3 to 14 microns.
The design has been derived in collaboration with the instrumentation group at
NOVA ASTRON, and partners at MPIA (Germany), CEA Saclay (France), KU
Leuven (Belgium) and ATC (UK). The work was performed for ESO as a phase-

2.10.8 GAIA
The Leiden Gaia group, led by Brown, is involved in the preparations for the
data processing for ESA's Gaia mission. Scheduled for launch in 2011, Gaia aims
at providing a stereoscopic census of the Milky Way galaxy by measuring highly
accurate astrometry (positions, parallaxes and proper motions), photometry and
radial velocities for one billion stars and other objects down to 20th magnitude.
In the past year, Brown, Busso, and Marrese continued their work on the
development of the data processing software for the photometric instrument of
Gaia in collaboration with groups in Rome, Teramo, Cambridge, and Barcelona.
The photometric data for Gaia will be collected through low dispersion
spectrophotometry with prisms and the group in Leiden is responsible for
developing the algorithms that extract the spectra from the raw data. A first
version of the processing algorithms developed in Leiden, Rome, and Teramo
were successfully integrated into the pipeline running in Cambridge and a test
of the algorithms on a 30 million star data set was run without significant
problems. Busso and Marrese completed a number of upgrades, related in
particular to the crowded field treatment, to the data processing algorithms.
Brown implemented a simplified version of some of the algorithms developed in
62
2.10 INSTRUMENTS AND FACILITIES
Leiden in the initial data treatment pipeline. The latter is the data processing
system that first receives the raw telemetry from Gaia and carries out important
pre-processing steps for which photometric information is needed.
Prod'homme addressed a major concern for the Gaia mission, the effect of
radiation damage to the CCDs (due to Solar wind and cosmic ray protons) by
conducting theoretical and empirical modeling of radiation damage effects.
These would lead to an increased level of charge transfer inefficiency causeing a
loss of signal as well as a distortion of the image. The latter will produce
systematic errors in the astrometry if not carefully controlled. Prod'homme
uded the CTI modelling tool CEMGA (CTI Effects Model for Gaia), developed
by himself, to analyze laboratory test data from EADS-Astrium in order to probe
the detailed physics of CTI. In addition, he used CEMGA to determine whether
the Cramer-Rao limit on the precision of the estimated location for stellar images
can still be reached in the presence of CTI. De Valk also used CEMGA, to study
the effect of CTI on the weak-lensing survey planned for the proposed EUCLID
space mission. The results were not conclusive but do indicate a need to
carefully consider this issue for EUCLID. Ter Haar studied the variance in the
CTI effects caused by the different orientations of the Gaia CCDs with respect to
the same field on the sky over the course of the mission. The results confirmed
the idea that the details of the so-called illumination history of the CCDs play an
important role in the systematic errors induced in the Gaia measurements.
Finally, Prod'homme also completed a first validation study of an approximate
but fast analytical model of CTI effects. This kind of model will be needed in the
Gaia data processing for which the detailed Monte Carlo model developed by
Prod'homme is too slow.
Risquez has been developing detailed simulations of Gaia's attitude,
incorporating all of the relevant physical effects, in collaboration with van
Leeuwen (Cambridge, UK) and Keil (Bremen, Germany. In order for Gaia to
reach its astrometric accuracy goals, the highest quality for the attitude
knowledge of the spacecraft is needed. It is thus important to incorporate a
complete physical understanding of the dynamics of a continuously rotating
space platform into the attitude modelling for Gaia. Risquez completed the
development of several modules that simulate specific physical effects in the
spacecraft attitude. These include: micro-meteoroid impacts, thermal infra-red
emission from the satellite surface, and noise due to the micro-propulsion
system. In addition, he implemented a model of Gaia's star-tracker and the onboard estimator of stellar image velocities in the focal plane (which serve as
input to the on-board attitude control system).
2.10 INSTRUMENTS AND FACILITIES
63
2.10.9 JWST-MIRI Testing
The mid-IR Instrument (MIRI) for the James Webb Space Telescope approaches
Flight Model (FM) Testing, preparing for a 2014 launch. As part of their
contribution to the MIRI Test Team, Martinez Galarza, Kendrew and Brandl
have analyzed a first set of data obtained using the Verification Model and
developed a method to measure the wavelength characterization of the
instrument's medium resolution IFU spectrometer (MRS) and low resolution slit
spectrometer (LRS). Comparison with optical models has shown that the actual
resolving power satisfies the requirements. Further analysis of FM data will
allow a full wavelength range characterization and a study of the unresolved
line profiles prior to delivery to NASA in early 2011.
2.11 Astrochemistry
2.11.1 Interstellar molecules formed on grains
Cuppen studied the formation of methanol (CH3OH) and its precursor
formaldehyde (H2CO) in dense cold cores. Many important molecules do not
form efficiently in the gas phase in the cold, dilute interstellar medium. Instead,
they require dust surfaces for their formation, but the detailed processes are still
unclear. Laboratory experiments provide ways to study these, but the results
are not always straightforward to interpret and the experiments themselves are
performed under conditions that still differ much from interstellar conditions.
Monte Carlo has been used successfully to disentangle the various mechanisms
and to extrapolate results to interstellar conditions, for instance in the case of H2,
H2O and CH3OH.
Cuppen conducted Monte Carlo simulations under a variety of conditions and
showed that both CH3OH and H2CO indeed form efficiently in cold dense
insterstallar cloud cores and in the cold outer envelopes of young stellar objects.
She discovered that dust grain mantles have a layered structure with CH3OH on
top, whereas molecular species such as CO and H2CO exist mainly in the lower
layers of ice mantles where they are not available for later hydrogenation. Her
findings differ from many gas-grain models which do not take into account the
layering of the ice. She found her model results to agree reasonably well with
observed solid H2CO/CH3OH and CO/CH3OH abundance ratios in the outer
envelopes of young stellar objects agree, and she concluded that the large range
in observed CH3OH/H2O abundance ratios may represent a range in
evolutionary stages.

2.11 ASTROCHEMISTRY
2.11.2 Simulations of Ice Photo-Dissociation
Arasa, Andersson, Cuppen, Kroes and van Dishoeck used classical molecular
dynamics simulations at different ice temperatures to clarify the photodesorption of water molecules in amorphous ice H photo-desorption provides
the most important channel in the uppermost ice layers, with probabilities a
hundred to a thousand times higher than those of OH and H2O photodesorption. It does not show a dependence on ice temperature. Arasa and
collaborators also compared the estimated total OH+H2O photo-desorption
probability per incident photon to the experimental yields measured by Oberg.
The experimental yields exceeded the theoretical probabilities by factors of 3-6.
Nevertheless, Arasa and coworkers concluded that, given the experimental
uncertainties and the theoretical approximations, the simulations agreed
reasonably well with the experimental results which are also typical for those
used in modelling astrophysical environments.

2.12.1 Laboratory Experiments
Conditions in space are extreme and not in favour of an efficient chemistry:
temperatures are low, radiation fields are intense and particle densities are
exceedingly low. Nevertheless, more than 150 different molecular species have
been identified in star-forming regions. These comprise both simple and
complex species as well as both stable and transient molecules and result from
exotic chemical evolution. Today, astrochemists explain the chemical complexity
in space as the cumulative outcome of gas, grain and gas-grain interactions. Gasphase models explain the observed abundances of the smaller as well as many of
the larger radical species. These models, however, fail to explain the presence of
stable and complex, partially organic species in space, such as acetonitrile, a
precursor molecule for the simplest amino acid glycine. It is now generally
accepted that such species form on icy dust grains, small solid particles that are
an important ingredient of the material found between the stars. These dust
particles play an essential role because they provide opacity (blocking regions of
the galaxy from UV radiation). They are also the basic material that form icy
planetesimals and ultimately planets and they provide catalytic sites for
molecule formation. Thermal and ultraviolet processing as well as atom
bombardment of icy dust grains trigger a fascinating solid state astrochemistry.
Understanding the cycle of matter in galaxies, the origin of stars and planetary
systems and the complex (organic) chemistry that is found in molecular clouds
and proto-planetary disks is intimately linked to the study of the role icy solids
have in space. A quantitative characterization of this role is only possible
through detailed laboratory studies and this is the research topic of the work
performed at the Sackler Laboratory for Astrophysics. The focus of the past year
has been 'Molecular Complexity in Space'.
2.12.2 UV Photo-Processing of Interstellar and Circumstellar Ice Analogues
In September, Öberg defended her thesis 'Complex Processes in Simple Ices'
describing UV-induced processes in ices under astronomical conditions: the
photo-desorption and photo-dissociation as well as the photo-chemistry of ices
(H2O, CO2 and CH3OH) upon UV irradiation. Her detailed analysis showed UVprocessed methanol ice to provide the basic elements for complex molecule
formation, as observed around young stellar objects. Öberg's work at the setup
CRYOPAD was continued by Fayolle who will focus on photo-induced
processes upon resonant ice excitation.
66
2.12 RAYMOND AND BEVERLY SACKLER LABORATORY
Figure 33. Karin Öberg addresses her favourite topic.
The team around the setup CESSS (Bouwman, Allamandola and Cuppen) has
been able to study the photophysical and photochemical behaviour upon UV
irradiation of polycyclic aromatic hydrocarbons included in an astronomical
water ice analogue. In situ and real time optical data provided insight in the role
PAHs play in the solid state and in addition provided an alternative route to
search for PAHs in space.
2.12.3 Atom Bombardment of Interstellar and Circumstellar Ice Analogues
The team around the SURFRESIDE setup (Ioppolo, Romanzin, Cuppen) focused
on water and methanol formation by hydrogenation reactions of oxygen/ozone
and carbon monoxide ice, respectively. They derived temperature-dependent
and flux-dependent reaction rates that elucidated the role of solid state reaction
schemes in the formation of water and methanol in space and extended the
results to astrochemical models. In parallel, they constructed a next generation
setup constructed which will allow them to study the simultaneous processing
of ices by H- and O/N-atoms.
Isokoski constructed a new ultrasensitive setup, MATRI2CES, with which to test
the influence of simultaneous UV irradiation and atom bombardment of an
interstellar/circumstellar ice analogue. The setup combines laser desorption and
time-of-flight detection and is expected to visualize chemical pathways towards
molecular complexity in much more detail than possible with the regular UHV
RAIRS and TPD techniques.
2.12.4 Molecular finger prints
Bottinelli, Bouwman and Beckwith made detailed ice spectroscopic
measurements on NH3 and CH3OH containing ices in order to identify
2.12 RAYMOND AND BEVERLY SACKLER LABORATORY
67
molecular signatures in recent Spitzer data. They found an unambiguous
presence in space of ammonia in the solid state. This was an important result, as
nitrogen-containing species are required in formation routes towards
biologically relevant species.
Wehres was able to measure vibronically excited C2 spectra on the LEXUS setup
and to compare these to emission features observed in the nebula known as the
Red Rectangle. Her laboratory data proved the presence of C2 in the outflows of
this proto-planetary nebula and also offered an analytical tool to describe
chemical processes as a function of the separation from the central star.
Finally, Guss has started to construct a new infrared laser detection scheme for
molecular transients in space on the setup SPIRAS. A cavity-enhanced detection
scheme, in combination with a planar plasma expansion, is used to search for
molecular fingerprints of transient species as may be detected by e.g. the HIFI
experiment on the Herschel Space Observatory

3.1. Education
Education and training of students is a major priority of Leiden Observatory. In
2009, 46 freshmen started their studies in astronomy. Of this number, 10 (22%)
are women, and 19 (41%) is pursuing a combined astronomy/physics or
astronomy/mathematics degree.
The Observatory registered a total number of 92 bachelor students at the end of
the year, including 42 (46%) aiming for a combined astronomy/physics degree.
A quarter of all BSc students is female. There were 36 MSc students, including
14 (39%) women and 12 (33%) foreign nationalities. In addition, there were still
two old-style doctoral students. Several students from the applied physics
department of Delft Technical University took courses of the Leiden astronomy
curriculum as part of the requirements for a minor in astronomy.
Twenty students passed their propedeutical exam, of which fully half completed
the requirements in the nominal one year. There were 10 BSc exams, and 7 MSc
exams. In addition, 4 students obtained the old-style degree of doctorandus.
At the beginning of the year, three staff members were acting part-time as study
advisers. However, Hogerheijde stepped down as freshman-student adviser in
summer. His tasks were taken over by Linnartz, who already was the study
adviser for the remainder of the Bachelor program. Portegies Zwart took over
from Röttgering as master-program study adviser. At the end of the year, the
number of student advisers was thus reduced from three to two. In November,
72
3.1 EDUCATION
Oosthoek left as education coordinator leaving a gap in the daily running of
tasks.
In addition to regular counseling by the student adviser, incoming students
were assigned to small groups meeting at regular intervals with a staff mentor
(Hoekstra, Icke, and Levin) and a senior student mentor. Student tutoring was
done by senior astronomy and physics students. In the tutor program, physics
and astronomy freshman students are provided, on a voluntary but regular
basis, with coaching by senior students.
As part of the introductory astronomy course, students were taken to the Artis
Planetarium in Amsterdam for a lesson in coordinate systems, time and constellations
in the sky (Hoekstra). As part of the second-year training in practical
astronomy, 12 honors students were offered the opportunity to take part in a
specially arranged observing trip to the Isaac-Newton-Telescope on La Palma,
Canary Islands (Van der Werf, de Mooij, van Haasteren).
The parallel course Analysis 3NA, provided by the mathematics department at
the specific request of both astronomy and physics, was very succesful. In this
course, (astro)physical applications of the mathematical tools are covered more
extensively than in the regular course which emphasizes mathemetical rigour.
Unlike the regular course Analysis 3, this parallel course does not prepare for
Analysis 4.
The astronomy curriculum is monitored by the ‘Opleidingscommissie’
(education committee), which advises the Director of Education on all relevant
matters, and which was chaired by Van der Werf. Other members are Icke,
Schaye, Franx, and Damen, as well as De Valk, Van den Broek, Straatman,
Langelaan and Pijloo for the student body. In the fall, the composition changed:
Van der Werf, Icke and Damen were replaced by Röttgering, Van Dishoeck and
Van Uitert respectively, and student representatives became Bremer, Pijloo,
Segers, and Vreeker. Under the authority of the Opleidingscomissie, the lecture
course monitoring system (SRS) was continued. In this system, students provide
feedback to lecturers during and after the course.
The quality of curriculum and exams is guarded by the Exam Committee
(Examencommissie) chaired by Lub, with Israel, Aarts (physics), Hogerheijde
and Röttgering as members.
Admission to the master-curriculum for students without a BSc in astronomy
from a Netherlands university requires a recommendation by the
'Toelatingscommissie’ (admissions committee) chaired by Schaye and having
Israel and Linnartz as members.

3.3 ACADEMIC COURSES AND PRE-UNIVERSITY PROGRAMS
77
3.3.2. Pre-University Programs
LAPP-Top, the Leiden Advanced Pre-University Program for Top Students,
is aimed at enthusiastic and ambitious high-school students from the
5th and 6th grade. Candidates are selected on the basis of their
high-school grades and their enthusiasm to participate. Students that
are selected will then take part in 6 to 8 meetings from January till
May, following the program of their own choice.
The Sterrewacht has been participating in the LAPP-TOP program since its start
in 2001. In that pilot year five students participated, in 2002/3 six, in 2003/4
eleven, in 2004/5 thirty-three, in 2005/6 seventeen, in 2006/7
twenty seven, in 2007/8 sixteen and in 2008/9 twenty.
The astronomy LAPP-TOP program was developed by Van der Werf from 2002
onward. From 2005-2008 the project was coordinated by Snellen. Since 2008 it is
coordinated by Franx. In eight sessions the following subjects were
treated:
Extrasolar planets – I. Snellen
The Milky Way and other galaxies – J. Schaye
Practicum: distances in the Universe
Gas and Radiation - V. Icke
Quasars, black holes and active galactic nuclei – H. Röttgering
Practicum: The black hole in the center of our Milky Way
Cosmology - P. Katgert
Excursion to the radio telescopes in Westerbork and Dwingeloo
After successfully completing the program participants have been awarded with
a certificate from the University of Leiden. High-school students are allowed to
use this project as part of their final exams.
3.3.3. Contact.Vwo
Contact.Vwo has been in existence for three years. Buisman and van der Hoorn
(physics teachers in secondary schools) both work one day a week for the
Physics and Astronomy Departments in order to intensify the contacts between
secondary schools and the university.
Van der Hoorn organizes twice yearly a production and mailing of posters and
organizes three times an informative meeting for physics teachers, starting at 6
78
3.3 ACADEMIC COURSES AND PRE-UNIVERSITY PROGRAMS
p.m. and featuring a lecture on modern developments in physics or
astrophysics, an informal dinner with extensive networking between teachers
and university workers, and after-dinner subjects dealing with the change from
secondary school to university study).
Buisman is concerned with school classes (programs for whole-day visits as well
as individual help (assisting pupils with practical work, answering questions by
mail etc.). He also has organized a training session for the module Measuring in
Star Systems (Meten aan Melkwegstelsels) which is part of the school
curriculum track Nature, Life and Technology (Natuur, Leven en Technologie).
Contact.Vwo answers ad hoc requests for assistance by school pupils or
teachers. Buisman also has an appointment for one day a week as local
coordinator of the HiSPARC project, but although related, this is not a part of
the activities of Contact.Vwo.

3.5. Universe Awareness Program
Universe Awareness:
Ödman and Miley continued their work on the Universe Awareness
programme.
Universe Awareness (UNAWE) is an international programme instigated by
Miley to expose underprivileged young children aged from 4 to 10 years to the
inspirational aspects of astronomy. By raising awareness about the scale and
beauty of the Universe, UNAWE attempts to broaden the mind and awaken
curiosity in science, at a formative age when the value system of children is
developing. A goal of UNAWE is to stimulate their development into curious,
tolerant and internationally minded adults.
Since its initiation by Miley in 2004, UNAWE has grown from a concept to a
thriving network of more than 200 UNAWE volunteers and experts active in
more than 35 partner countries worldwide. Some important achievements of
UNAWE during 2009 were:
(i) The addition of several new partner countries to the programme
(ii) The organization of many international UNAWE events for young children
(iii) The implementation of UNAWE as a global cornerstone programme of the
UN-designated International Year of Astronomy in 2009
(iv) Development of a range of international UNAWE materials and activities,
instigation of a sustained development of new materials
(v) Lobbying for acquisition of EU funding

3.6 IAU STRATEGIC PLAN
3.6. IAU Strategic Plan: Astronomy for the
Developing World
As the responsible IAU Vice President, George Miley led the development of a
new strategy to use astronomy for international development and education.
This was formalized as the IAU decadal strategic plan, “Astronomy for the
Developing World – Building from IYA 2009”. The plan was written and edited
by Miley and endorsed overwhelmingly at the IAU General Assembly at Rio de
Janeiro in August. It shows that astronomy can make a unique contribution to
building the technological, scientific and cultural capacities of developing
countries.
The plan lays out an ambitious plan to exploit astronomy for such ends during
2010 – 2020, with contributions at every level (primary, secondary and tertiary
education, research infrastructure and public outreach).
Elements of the strategy include:
1. An integrated strategic phased approach
2. Increase regional involvement
3. Building on the momentum generated by the IYA by continuing IYA
cornerstone projects, exploiting the IYA network of 148 countries and the
alliance between professional and non-professional astronomer,
4. Enlarging the number of active volunteers
5. Initiating several new activities, including semi-popular lectures in
developing countries and long-term institute twinning between developed
astronomy organizations and departments in developing countries
6. Advancing the UN Millennium Goals
7. Exploit new tools and opportunities, including mobile planetaria and internet
educational telescope networks and
8. Creating small global “Office for Astronomy Development” and regional
nodes throughout the world.
Following on from the highly successful International Year of Astronomy 2009,
the new plan is a pioneering international venture seeks to exploit scientists and
pure research for the benefit of global development.
3. 7 THE LEIDSCH ASTRONOMISCH DISPUUT ‘F. KAISER’
87
3.7. The Leidsch Astronomisch Dispuut ‘F.
Kaiser’
With only one significant activity, this might well be the simplest annual report
of L.A.D. F. Kaiser in years. In early february 2009 the Old Observatory closed
its doors for a well deserved renovation, but this left Kaiser without its star
attraction. This meant no observing nights and tours for some time to come.
Despite this, the board organised the annual soccer tournament. This
tournament was a huge success and a week later it was still easy to tell who had
participated and who hadn't. Unfortunately the Kaiser team lost, but not
without an heroic battle, making two board members limp for a few weeks. The
winner was the Sterrewacht team "The Smokers", who ironically didn't have to
catch their breath afterwards.
In the course of the year, two board members got a PhD position in Leiden,
which made it harder to find time to organise events. Therefore in 2010 we will
be looking for new board members to take over the torch and entertain us with
new exciting activities.
3.8 Vereniging van Oud-Sterrewachters
The 'Vereniging van Oud-Sterrewachters' (VO-S; http://www.vo-s.nl/) is the
official association of Sterrewacht/Observatory (ex-)affiliates.
It has been in existence for over 15 years now and has seen another active year.
As usual, the 150 members were offered a variety of activities. The activities
included a social drink prior to the Oort Lecture and an annual meeting. This
year, the annual meeting was held in Leiden and involved, among others, a visit
of Museum Naturalis. The meeting was attended by 30 members. VO-S
members also received a newsletters with Sterrewacht news and were offered an
electronic member dictionary.
