From Large Volumes to Near Field Cosmology

During the last years we run a series of dark matter simulations with 3840^3 particles within volumes of (2500/h Mpc)^3, (1000/h Mpc)^3), (400/h Mpc)^3 and (160/h Mpc)^3. Recently we have extendend this MultiDark project to an even smaller volume of (64/h Mpc)^3 and combined it with the CLUES project ( from which the constrained initial conditions have been provided. In the resulting simulation both a numerical counterpart of the Virgo cluster and of the Local Group can be identified and allow study of Near Field Cosmology. I am going to review results from these projects. I will also briefly introduce the CosmoSim database from which access to the simulations is possible.
