  We model the two-point correlation function of galaxies in a cold dark matter
Universe by combining two powerful theoretical tools - dissipationless N-body
simulations of dark matter clustering (specifically the GIF simulations carried
out by MPIA and the Virgo Consortium) and semi-analytic modelling of galaxy
formation. We construct catalogues of galaxies containing a wide range of
information for each galaxy, including magnitudes in various bands, star
formation rates, disk and bulge sizes (from the semi-analytic model described
by Cole et al 1998) and, importantly, spatial positions and peculiar velocities
from the N-body simulation. We then use this information to study the
clustering properties of galaxies.
