ABSTRACT
The clustering of galaxies reflects both the cosmological parameters
that govern the spatial distribution of dark matter halos and the
complex physics of galaxy formation. Changes in galaxy clustering
properties with time can be used to understand the evolution of
galaxies and constrain theoretical models and simulations. I will
discuss recent results on galaxy and AGN clustering at z=1 using data
from the DEEP2 Redshift Survey. I will show how the clustering
depends on galaxy luminosity, color and scale 8 Gyr ago and compare
these results to local SDSS findings and models of the halo occupation
distribution. I will also discuss the relative clustering bias of
quasars and X ray-selected AGN to star-forming and quiescent galaxies
at z=1, which constrains the types of galaxies that host quasars and
AGN, leads to estimates of their host dark matter halo masses, and
strongly informs AGN formation models.
