NED Abstract

Copyright by Royal Astronomical Society. 2012MNRAS.427.1298H The Canadian Cluster Comparison Project: weak lensing masses and SZ scaling relations Hoekstra, Henk; Mahdavi, Andisheh; Babul, Arif; Bildfell, Chris Abstract. 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 +/- 5 per cent at ~r_2500_, 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. Key words: gravitational lensing: weak, galaxies: clusters: general, cosmology: observations, dark matter
