Scientific paper

The Dark Energy Survey (DES) is a proposed 5-year, 5000 deg 2 optical imaging survey, to 24th magnitude in the SDSS griz bands, that will use a new wide-field 3 deg2 mosaic CCD camera on the Blanco 4m telescope at the Cerror Tololo Inter-American Observatory (CTIO). The primary scientific goal of the DES is to probe the nature of dark energy using four complementary methods: galaxy clusters, weak gravitational lensing, galaxy angular correlations, and Type Ia supernovae. For each of these methods, the DES should determine the dark energy equation of state parameter w with a statistical precision of about 5-15%, assuming constant w but without strong priors on other cosmological parameters. By deriving dark energy constraints using four complementary sets of measurements made from the same data set and within a common analysis framework, we will obtain important crosschecks of our systematic errors and thereby make a substantial and robust advance in the precision of dark energy measurements.
