Scientific paper

We combine semi-analytic models of galaxy formation with N-body simulations of cosmic structure formation to explore both the clustering properties of galaxies and their global properties. Two Cold Dark Matter Universes provide redshift survey mock catalogs whose redshift space correlation functions and galaxy group catalogs are in reasonable agreement with the results obtained with the Center for Astrophysics redshift surveys. We show that the internal properties of groups of galaxies are extremely sensitive to the galaxy formation recipe. Therefore, a better understanding of the properties of real groups can shed light on the complexity of galaxy formation processes.
