Richness-mass relation self-calibration for galaxy clusters    [PDF]

S. Andreon, J. Bergé

This work attains a threefold objective: first, we derived the richness-mass scaling in the local Universe from data of 53 clusters with individual measurements of mass. We found a 0.46+-0.12 slope and a 0.25+-0.03 dex scatter measuring richness with a previously developed method. Second, we showed on a real sample of 250 0.06View original: http://arxiv.org/abs/1209.5938
