A measurement of the mean central optical depth of galaxy clusters via the pairwise kinematic Sunyaev-Zel’dovich effect with SPT-3G and DES

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: E. Schiappucci, F. Bianchini, M. Aguena, M. Archipley, L. Balkenhol | Summary: We infer the mean optical depth of a sample of optically-selected galaxy clusters from the Dark Energy Survey (DES) via the pairwise kinematic Sunyaev-Zel’dovich (kSZ) effect. The pairwise kSZ signal between pairs of clusters drawn […]
