Weak lensing of SDSS galaxy clusters. III.

DOI

We present measurements of the excess mass-to-light ratio (M/L) measured around MaxBCG galaxy clusters observed in the Sloan Digital Sky Survey. This red-sequence cluster sample includes objects from small groups with M_200_~5x10^12^/hM_{sun} to clusters with M_200~10^15^/hM_{sun}_. Using cross-correlation weak lensing, we measure the excess mass density profile above the universal mean {Delta}{rho}(r)={rho}(r)-{bar}{rho} for clusters in bins of richness and optical luminosity. We also measure the excess luminosity density {Delta}l(r)=l(r)-{bar}l measured in the z=0.25 i band. For both mass and light, we de-project the profiles to produce three-dimensional mass and light profiles over scales from 25h^-1^kpc to 22h^-1^Mpc. From these profiles we calculate the cumulative excess mass {Delta}M(r) and excess light {Delta}L(r) as a function of separation from the BCG.
