The DEEP2 Redshift Survey is the first project to study a large set of
galaxies in the distant universe with spatial sampling and spectral
resolution comparable to that achieved locally. DEEP2 was designed to
measure both the properties of distant galaxies and their distribution
in space, making possible a number of unique tests of both galaxy
formation and the properties of the Universe. Using DEIMOS, a new
instrument at the Keck Observatory, we are obtaining spectra of 50,000
galaxies with R_AB<24.1, most at redshift 0.7 < z < 1.4; the survey is
now more than 95% complete. One of the DEEP2 fields, the Extended
Groth Strip, is the focus of an intensive multiwavelength campaign
spanning from X-ray to radio wavelengths, including the IRAC GTO
observations based at CfA. In this talk, I will provide a brief
description of DEEP2. I will also describe a few of our most recent
results, including a sample of groups and clusters of galaxies at high
redshift (which can be used to measure the Dark Energy equation of
state); measurements of the interdependence between galaxy properties
and environment at z~1; and a test for evolution in the Fine
Structure Constant over cosmic timescales.
