The Dark Energy Surveys: new results
The proposed session will present new results from the Dark Energy Survey (DES). The survey has nearly completed 3 out of the planned 5 observing seasons (as of January 2016). DES is using a wide-field camera on the 4m Blanco Telescope in Chile to image 5000 sq deg of the sky in five filters. By its completion the survey is expected to have generated a catalogue of 300 million galaxies with photometric redshifts and 100 million stars. In addition, a time-domain survey search over 27 sq deg is expected to yield a sample of thousands of Type Ia supernovae and other transients. The main goals of DES are to characterise dark energy and dark matter, and to test alternative models of gravity; these goals are being pursued by studying large scale structure, cluster counts, weak gravitational lensing and Type Ia supernovae.

However, DES also provides a rich data set which allows us to study many other aspects of astrophysics. Highlights from DES early data include the discovery of Solar System objects, dwarf satellites of the Milky Way, high-redshift quasars and superluminous supernovae. About 60 DES papers have already appeared in the publlc domain.
