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.
