Scientific paper

We have carried out a 10 billion particle simulation of the growth of dark matter structure in the concordance ΛCDM cosmology with 125 times better mass resolution than the existing Millennium Simulation. By combining these two calculations and using semi-analytic techniques we are able to simulate the formation and evolution of the galaxy population on all scales, from the smallest dwarf spheroidals to the most massive cD galaxies. We study the physical requirements to get agreement with observations of the luminosities, metallicities, morphologies, star formation rates and clustering of galaxies both at z=0 and at higher redshift, focusing in particular on the dwarf galaxies which could not be treated in previous work. By analysing these properties across the full observed luminosity range, we are able to constrain processes as diverse as cosmic reionization, the life times of type Ia supernovae and the effects of energetic outflows from black holes.
