124 V. People and Events These opportunities were decisive in convincing van den Bosch to apply for the position. At the same time, the MPIA is the ideal workplace for him: the Institute is participating in the Sloan Digital Sky Survey and other galaxy surveys, and it is equipped with large, up-to-date Beowulf-supercomputers. Moreover, the existence of other theory groups ensures a vibrant environment for intellectual interchange. Van den Bosch has broad experience in his field. In 1997, he received his PhD from Leiden Observatory. Afterwards he went to the University of Washington as a Hubble Fellow. Stays at the MPI for Astrophysics (Garching) and the ETH (Zurich) followed before he came to the MPIA. Here he plans to focus on various aspects of cosmology. A primary subject of his research is the structure and formation of disk galaxies. In these systems stars and gas circle around the center. The key to understanding these galaxies is therefore the question of how the angular momentum has developed and which factors affect it. Van den Bosch and his group will tackle these problems using a combination of analytical methods and numeric calculations. The observed relations between the sizes, luminosities and rotation velocities may be of crucial importance for this. Another focus of his research is the connection between galaxies and dark matter halos. For this, van den Bosch has developed a new statistical method based on the properties of galaxy clustering. The resulting statistical description of the so-called galaxy-dark matter connection yields strong constraints on the theory of galaxy formation. The same technique can also be used to constrain cosmological parameters, such as the matter density of the universe. In the years to come, van den Bosch wants to improve these and similar methods and apply them to large redshift surveys, such as the 2dF Galaxy Redshift Survey and the Sloan Digital Sky Survey. A third major research subject of van den Bosch is the formation and structure of dark matter halos, which he addresses using a combination of numerical simulations and semi-analytical techniques.

V.8 Prizes for Young Scientists Scientific awards have various purposes. They encourage the recipients in their work and give them confidence for future career prospects. At the same time, they often are an important means of support to enable students and post-docs from Germany and abroad to work at a certain institute. For the MPIA, the year 2005 has been quite successful in this respect. Sebastian Wolf was awarded the Heinz Maier-Leibnitz Prize, and Elena Masciadri the Marie Curie Excellence Grant, while the Ernst Patzer Prize for Supporting Junior Scientists at the MPIA went to Jorge Penarrubia, Marco Barden, and Anders Johansen. Heinz Maier-Leibnitz Prize for Sebastian Wolf Since 1977, the Heinz Maier-Leibnitz Prize has honored young scientists in recognition of their excellent work. It is the most prestigious price for young scientists in Germany. The award includes a prize money of 16 000 euros and is intended to promote the prizewinners' further scientific career. The prize funds are provided by the Federal Ministry of Education and Research. In 2005, the presentation of the prizes took place on June 6 th in Bonn. The jury acknowledged Wolf's significant work on the study and modeling of protoplanetary disks in the field of planet and star formation. It placed particular emphasis on the fact that his work stands out because of its originality and the high level of the physical-mathematical treatment of the complex problem. Sebastian Wolf studied physics at the University of Jena. After periods of research at several institutes such as the European Southern Observatory (eso) and the California Institute of Technology in Pasadena, he came to the MPIA in 2002. Since 2004, he has been the head of an Emmy Noether Junior Scientists Group dealing with circumstellar dust disks evolving into planetary systems (see Annual Report 2004, p. 107). Sebastian Wolf deals with the complex problem of planet formation. His working method is based on a combination of numerical simulations on the one hand and astronomical observations on the other. In order to better study the dust component of a protoplanetary disk, he developed a novel simulation program that allows the radiation transport within the dust disks around Fig. V.8.1: Ernst-Ludwig Winnaker, President of the German Research Association (DFG) presents the Heinz Maier-Leibnitz Prize to Sebastian Wolf.
