The Sloan Nearby Cluster Weak Lensing Survey
Abstract
We describe and present initial results of a weak lensing survey of nearby (z lsim 0.1) galaxy clusters in the Sloan Digital Sky Survey (SDSS). In this first study, galaxy clusters are selected from the SDSS spectroscopic galaxy cluster catalogs of Miller et al. and Berlind et al. We report a total of seven individual low-redshift cluster weak lensing measurements that include A2048, A1767, A2244, A1066, A2199, and two clusters specifically identified with the C4 algorithm. Our program of weak lensing of nearby galaxy clusters in the SDSS will eventually reach ~200 clusters, making it the largest weak lensing survey of individual galaxy clusters to date.
