Weak Lensing Analysis of SPT selected Galaxy Clusters using Dark Energy Survey Science Verification Data
International audience We present weak-lensing (WL) mass constraints for a sample of massive galaxy clusters detected by the South Pole Telescope (SPT) via the Sunyaev–Zel’dovich effect (SZE). We use griz imaging data obtained from the Science Verification (SV) phase of the Dark Energy Survey (DES)...
