Wide-Field Lensing Mass Maps from Dark Energy Survey Science Verification Data
Wide-Field Lensing Mass Maps from Dark Energy Survey Science Verification Data
We present a mass map reconstructed from weak gravitational lensing shear measurements over 139 sq. deg from the Dark Energy Survey (DES) Science Verification data. The mass map probes both luminous and dark matter, thus providing a tool for studying cosmology. We find good agreement between the mass map and …
