The Dark Energy Survey: Status and new gravitational lensing results

The Dark Energy Survey is in the process of imaging 5000 sq. deg. of the southern sky in five broad-band filters. Its primary purpose is to constrain cosmology and the physics of dark energy using weak gravitational lensing, galaxy clusters, baryonic acoustic oscillations, and supernova distance measurements. I will give an overview of the recently released early results on the Science Verification data set and upcoming work on the main survey data, with a focus on weak gravitational lensing and the newly developed statistics of galaxy troughs.
