The Dark Energy Survey: New Results
This session will present new results from the Dark Energy Survey (DES).
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.
The survey has nearly completed 4 out of the planned 5 observing seasons.
Highlights from DES early data include the discovery of Solar System Objects, dwarf satellites of the Milky Way, z > 6 quasars and superluminous supernovae.
89 DES papers have already appeared in the publlc domain.
