The Canadian Cluster Comparison Project: weak lensing masses and SZ scaling relations.

Abstract (from CDS):

The Canadian Cluster Comparison Project is a comprehensive multi-wavelength survey targeting 50 massive X-ray selected clusters of galaxies to examine baryonic tracers of cluster mass and to probe the cluster-to-cluster variation in the thermal properties of the hot intra-cluster medium. In this paper we present the weak lensing masses, based on the analysis of deep wide field imaging data obtained using the Canada–France–Hawaii Telescope. The final sample includes two additional clusters that were located in the field-of-view. We take these masses as our reference for the comparison of cluster properties at other wavelengths. In this paper we limit the comparison to published measurements of the Sunyaev–Zel'dovich effect. We find that this signal correlates well with the projected lensing mass, with an intrinsic scatter of 12±5percent at ∼ r2500, demonstrating it is an excellent proxy for cluster mass.

Based on observations from the Canada–France–Hawaii Telescope, which is operated by the National Research Council of Canada, le Centre National de la Recherche Scientifique and the University of Hawaii.
