The DEEP2 galaxy redshift survey:: Clustering of galaxies as a function of luminosity at z=1

We measure the clustering of DEEP2 galaxies at z = 1 as a function of luminosity on scales 0.1-20 h(-1) Mpc. Drawing from a parent catalog of 25,000 galaxies at 0.7 < z < 1.3 in the full DEEP2 survey, we create volume-limited samples having upper luminosity limits between M-B = -19 and -20.5, roughly 0.2 - 1L* at z = 1. We find that brighter galaxies are more strongly clustered than fainter galaxies and that the slope of the correlation function does not depend on luminosity for L < L*. The brightest galaxies, with L < L*, have a steeper slope. The clustering scale length, r(0), varies from 3.69 +/- 0.14 for the faintest sample to 4.43 +/- 0.14 for the brightest sample. The relative bias of galaxies as a function of L/L* is steeper than the relation found locally for SDSS galaxies by Zehavi et al. in 2005 over the luminosity range that we sample. The absolute bias of galaxies at z similar to 1 is scale dependent on scales r(p) < 1 h(-1) Mpc, 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 similar to(1-3) x 10(12) h(-1) M circle dot.
