GRK 787:

Subject Area
Condensed Matter Physics
Term
from 2002 to 2005
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 273455
The physical processes of structure formation in the Universe from Big Bang to the present time are largely unkown up to now. Mayor research topics concern the formation of the observed large variety of galaxy properties and the nature of dark matter. In this context especially galaxy groups - small, gravitationally bound aggregates of galaxies and their satellites - play a special role. Galaxy groups are, contrary to the much more massive galaxy clusters, lessevolved and dominated by individual events. This implies that the evolutionary effects like gravitational interaction and interaction with the intergroup medium can be studied in detail. Galaxy groups are also important systems for our understanding of structure formation since they sample the lower density peaks of the primoridal density distribution.
