Query: The DEEP2 Galaxy Redshift Survey: The Relationship Between Galaxy
  Properties and Environment at z ~ 1   We study the mean environment of galaxies in the DEEP2 Galaxy Redshift Survey
as a function of rest-frame color, luminosity, and [OII] equivalent width. The
local galaxy overdensity for >14,000 galaxies at 0.75 < z < 1.35 is estimated
using the projected 3rd-nearest-neighbor surface density. Of the galaxy
properties studied, mean environment is found to depend most strongly on galaxy
color; all major features of the correlation between mean overdensity and
rest-frame color observed in the local universe were already in place at z ~ 1.
In contrast to local results, we find a substantial slope in the mean
dependence of environment on luminosity for blue, star-forming galaxies at z ~
1, with brighter blue galaxies being found on average in regions of greater
overdensity. We discuss the roles of galaxy clusters and groups in establishing
the observed correlations between environment and galaxy properties at high
redshift, and we also explore the evidence for a ``downsizing of quenching''
from z ~ 1 to z ~ 0. Our results add weight to existing evidence that the
mechanism(s) that result in star-formation quenching are efficient in group
environments as well as clusters. This work is the first of its kind at high
redshift and represents the first in a series of papers addressing the role of
environment in galaxy formation at 0 < z < 1.
