Title: "The Mass of the Coma Cluster from Weak Lensing in SDSS"

Abstract:

We present a weak lensing analysis of the Coma Cluster (z=0.0236) using the Sloan Digital Sky Survey (SDSS). Complete imaging of a ~200 square degree region of the SDSS is used to measure the weak lensing shear of this galaxy cluster. The shear is used to determine the mass of Coma and we compare this result with previous dynamical methods used determine the mass. This is the lowest redshift galaxy cluster ever measured with weak lensing.
