large-scale structure
  Brown dwarfs and low-mass stars; high proper motion survey compared with near-infrared sky surveys; formation of massive stars and their influence on galaxy evolution; distance-calibrators in the form of the Cepheid period-luminosity relation; star formation in the early universe      Structure of the Milky Way galaxy and of its components; surveys for quasars and Active Galactic Nuclei; host galaxies and environments of AGN; clusters of galaxies; X-ray observations of compact objects; numerical simulations of galaxy formation and evolution.      Morphology and evolution of large-scale structure, formation of first stars and galaxies, intergalactic medium and background radiation, galaxy formation in a cosmological environment, dark matter halos and dark energy effects in cosmology.
  Selected projects
CLUES    Constellation    eROSITA    GALOCS
  Constrained Local UniversE Simulations; the observed distribution of nearby galaxies is used to construct the initial conditions for these simulations      International collaboration for the study of the origin of stellar masses and their distribution      The mission will provide the first sky survey of intermediate x-ray energies up to 10 keV with high resolution.      GALactic Open Cluster Study; German-Russian collaboration supported by DFG; investigation of the population of open clusters in the Solar neighbourhood
  Galaxy Evolution from Morphology and SEDs: An investigation of the largest colour mosaic image ever obtained with the Hubble Space Telescope.      The Multi Unit Spectroscopic Explorer is a second generation instrument in development for the Very Large Telescope (VLT).      The RAdial Velocity Experiment is a survey to measure the radial velocities, metallicities and abundance ratios for up to 1 mill. stars      The Sloan Digital Sky Survey provides detailed optical images of more than 1/4 of the sky, and a 3D map of about 1 mill. galaxies and quasars.
  Space Telescope A901/902 Galaxy Evolution Survey: a multiwavelength survey to probe the physical drivers of galaxy evolution in dense environments      VIRUS will be a giant integral-field unit spectrograph for the optical light      XMM Survey Science Center at AIP provides the source detection software for the pipe-line processing of the XMM EPIC data.
