| The DEEP2 Galaxy Redshift Survey: color and luminosity dependence of galaxy clustering at z similar to 1 (2008) | |||||||||||||||
Abstract | |||||||||||||||
| We present measurements of the color and luminosity dependence of galaxy clustering at z∼ 1 in the DEEP2 Galaxy Redshift Survey. Using volume-limited subsamples in bins of both color and luminosity, we find the following: (1) The clustering dependence is much stronger with color than with luminosity and is as strong with color at z∼1 as is found locally. We find no dependence of the clustering amplitude on color for galaxies on the red sequence, but a significant dependence on color for galaxies within the blue cloud. (2) For galaxies in the range L/L*∼ 0.7-2, a stronger large-scale luminosity dependence is seen for all galaxies than is seen for red and blue galaxies separately. The small-scale clustering amplitude depends significantly on luminosity for blue galaxies, with brighter samples having a stronger rise on scales rp ‹0.5 h-1 Mpc. (3) Redder galaxies exhibit stronger small-scale redshift-space distortions ("fingers of god"), and both red and blue populations show large-scale distortions in ζ(rp, ϖ) due to coherent infall.
