The Dark Energy Survey
The Dark Energy Survey is proposing to constrain dark energy with four complementary probes: galaxy cluster counts, weak lensing, galaxy clustering and Type Ia Supernovae. In order to achieve this a new 3 deg CCD camera will be mounted on the Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory (CTIO). The camera will be sensitive up to 24 magnitude in the g,r,i and z bands. The ...
متن کاملThe Dark Energy Survey Data Management System
The Dark Energy Survey (DES) collaboration will study cosmic acceleration with a 5000 deg griZY survey in the southern sky over 525 nights from 2011-2016. The DES data management (DESDM) system will be used to process and archive these data and the resulting science ready data products. The DESDM system consists of an integrated archive, a processing framework, an ensemble of astronomy codes an...
متن کاملThe Dark Energy Survey Science Program
The Dark Energy Survey (DES) will enable measurements of the dark energy and dark matter densities and the dark energy equation of state through four independent methods: galaxy clusters, weak gravitational lensing, galaxy angular clustering (baryon acoustic oscillations), and supernovae. These methods, highlighted by the Dark Energy Task Force Report (DETF) as the most promising, are doubly co...
متن کاملThe Dark Energy Survey Instrument Design
We describe a new project, the Dark Energy Survey (DES), aimed at measuring the dark energy equation of state parameter, w, to a statistical precision of ~5%, with four complementary techniques. The survey will use a new 3 sq. deg. mosaic camera (DECam) mounted at the prime focus of the Blanco 4m telescope at the Cerro-Tololo International Observatory (CTIO). DECam includes a large mosaic camer...
متن کاملA search for kilonovae in the Dark Energy Survey
The coalescence of a binary neutron star pair is expected to produce gravitational waves (GW) and electromagnetic radiation, both of which may be detectable with currently available instruments. We describe a search for a predicted r-process optical transient from these mergers, dubbed the “kilonova” (KN), using griz broadband data from the Dark Energy Survey Supernova Program (DES-SN). Some mo...
