[69.15] The Science of the Dark Energy Survey

J. Frieman (Fermilab/Chicago), Dark Energy Survey Collaboration

The Dark Energy Survey (DES) is a 5000 sq. deg. griz imaging survey to be conducted using a proposed 3 sq. deg. wide-field mosaic camera on the CTIO Blanco 4m telescope. The primary scientific goal of the DES is to constrain dark energy cosmological parameters via 4 complementary methods: galaxy clusters, weak lensing, galaxy angular correlations, and Type Ia supernovae, supported by precision photometric redshifts. Individually these will probe w at the 5-15% level; collectively they can in principle reach the few percent level. The DES is the next step in precision measurements of dark energy.
