Dark Energy Survey completes six year mission

Scientists’ effort to map a portion of the sky in unprecedented detail is coming to an end, but their work to learn more about the expansion of the universe has just begun. After scanning in depth about a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies, the Dark Energy Survey (DES) will finish taking data tomorrow, on Jan. 9.

We’ve been reminiscing on our 6 years of observations and shared some of our memories from the mountain here.

DES Gravitational Waves Papers

This page serves as the portal for a series of 6 papers in relation to the gravitational wave (GW) event. The LIGO-VIRGO Collaboration (LVC) issued a trigger known as GW170817, a candidate binary neutron star event discovered on Aug. 17, 2017. DES-GW followed this up based on the sky localization provided by LVC and was one of a few groups that rapidly and independently identified an associated optical transient in the galaxy NGC 4993. Over the following nights, this object was repeatedly observed for the DES-GW program with DECam and the fading light curve measured.

DES Year 1 Cosmology Results: Papers

This page serves as the portal for a series of 10 papers on and in support of the DES cosmology results from the first year (Y1) of the survey, which were released on Aug. 3, 2017. For each paper, clicking on ‘Link’ will take you to the arXiv, where the pdfs can be accessed. On Thurs., Aug. 3, 2017, Daniel Gruen delivered a talk on these results at the APS Division of Particles & Fields meeting at Fermilab. A video of this talk as well as the slides can be accessed here, as well as in our Video Gallery, where you can find all our DES videos.
