Constraining Cosmological Parameters Using the Cluster Mass–Richness Relation

Constraining Cosmological Parameters Using the Cluster Mass–Richness Relation

The cluster mass–richness relation (MRR) is an observationally efficient and potentially powerful cosmological tool for constraining the matter density Ω _m and the amplitude of fluctuations σ _8 using the cluster abundance technique. We derive the MRR relation using GalWCat19 , a publicly available...
