Large-scale simulation of the evolution of the galaxy population

Advances in computer power and in simulation algorithms have made it possible to carry out simulations of the formation and evolution of galaxies throughout regions as large as those mapped by recent surveys of the local Universe. I will show results of the first ever direct numerical solution of the Newtonian gravitational N-body problem with N > 10,000,000,000, a representation of evolution of the dark matter distribution in a region 700 Mpc across according to the current, concordance cosmological model. Modelling galaxy formation within this simulation allows the physics of many of the connections between galaxy properties and galaxy clustering, as well as between high and low redshift objects, to be understood.
