[106.07] Environmental Dependence of Galaxy Properties at z ~0 to z ~1

M. C. Cooper (UC-Berkeley), DEEP2 Team

We investigate the environmental dependence of galaxy properties within magnitude-limited samples selected from the DEEP2 and 2dF Galaxy Redshift Surveys. Galaxy environment is defined according to the unique volume occupied by each galaxy in redshift space, using a Voronoi partition of the two survey volumes. In this talk, we present detailed comparisons with popular density estimators, and we investigate the environmental dependence of star-formation rate, internal kinematics, and the galaxy luminosity function over the redshift range z ~0 to z ~1. This work is being supported by funding from the National Science Foundation (NSF).
