Abstract

We use the abundance and weak-lensing mass measurements of the Sloan Digital Sky Survey maxBCG cluster catalog to simultaneously constrain cosmology and the richness-mass relation of the clusters. Assuming a flat ACDM cosmology, we find sigma(8)(Omega(m)/0.25)(0.41) = 0.832 +/- 0.033 after marginalization over all systematics. In common w...More
