TITLE: The Dark Energy Survey 

ABSTRACT: The Dark Energy Survey Collaboration built the Dark Energy Camera (DECam), a 3 square degree, 570 Megapixel CCD camera for the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory in Chile. DECam was installed on the telescope in 2012 and is being used to carry out a 5 year, 5000 sq. deg. survey, the largest imaging survey by cosmological volume to date. The 4th year of observing is complete and analysis of the data is in progress. By observing and studying the properties of hundreds of millions of galaxies, tens of thousands of galaxy clusters, and thousands of type 1A supernovae, the DES collaboration is working towards measurement of cosmological parameters with percent-level precision. This talk will present the status of the survey, recent DES results and prospects for the full dataset.
