The DEEP2 Galaxy Redshift Survey: Clustering of Galaxies as a Function of Luminosity atz= 1

We measure the clustering of DEEP2 galaxies at z=1 as a function of luminosity on scales 0. 05 Mpc/h to 20 Mpc/h. Drawing from a parent catalog of 25, 000 galaxies at 0. 7L^*, show a steeper slope and a strong rise in clustering amplitude on small scales. The relative bias of galaxies as a function of L/L^* is steeper than the relation found locally for SDSS galaxies (Zehavi et al. 2005) over the luminosity range that we sample. The absolute bias of galaxies at z=1 is scale-dependent on scales rₚ<1 Mpc/h, and rises most significantly on small scales for the brightest samples. For a concordance cosmology, the large-scale bias varies from 1. 26 +/-0. 04 to 1. 54 +/-0. 05 as a function of luminosity and implies that DEEP2 galaxies reside in dark matter halos with a minimum mass of ~1-3 10¹2 h^-1 Mₛun.
