Abstract

ASTRONOMY AND ASTROPHYSICS clusters cosmology: observations galaxies: clusters: general galaxy gravitational gravitational lensing: weak lensing mass redmapper redshift
We constrain the mass--richness scaling relation of redMaPPer galaxy clusters identified in the Dark Energy Survey Year 1 data using weak gravitational lensing. We split clusters into 4×3 bins of richness λ and redshift z for λ≥20 and 0.2≤z≤0.65 and measure the mean masses of these bins using their stacked weak lensing signal.
