The Dark Energy Survey (DES) is a ~5000 square degree optical -near infrared (grizY-band) survey of the Southern Sky. The survey, conducted using the DECam imager on the 4 m telescope at Cerro Tololo Inter-American Observatory in Chile, is scheduled for completion in January 2019. DES uses a range of observables including Type 1a SNe, galaxy clustering, cosmic shear, and galaxy clusters to probe cosmological models. The Argonne group has been involved in a number of these efforts and is also especially interested in combining data from DES with that from the South Pole Telescope to maximize cosmological constraints. Previous results include the first observation of the pairwise kinematic Sunyaev-Zel’dovich effect using a photometric survey.
