Title:

Galaxy and Quasar Clustering at z = 1

Abstract:

 The clustering of galaxies has long been used as a fundamental measure
 of the large-scale structure of the Universe.  Clustering properties
 reflect both the cosmological parameters that govern the spatial
 distribution of dark matter halos and the complex physics of galaxy
 formation.  Changes in galaxy clustering with time are key
 diagnostics for theoretical models of galaxy evolution.  I will
 present recent results on galaxy clustering properties at z=1 using
 data from the DEEP2 Redshift Survey undertaken at the Keck
 Observatory.  I will show how the clustering depends on galaxy
 luminosity, color and scale at redshift unity 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 'normal' galaxies at z=1, which
 constrains the types of galaxies that can host quasars and AGN, leads
 to estimates of their host dark matter halo masses, and strongly
 informs AGN formation models.
