The XXL Survey: IV. Mass-temperature relation of the bright cluster sample

Context. The XXL Survey is the largest survey carried out by XMM-Newton. Covering an area of 50 deg super(2), the survey contains ~450 galaxy clusters out to a redshift ~2 and to an X-ray flux limit of ~ 5 x 10 super(-15) erg s super(-1) cm super(-2). This paper is part of the first release of XXL r...

Description
Summary:Context. The XXL Survey is the largest survey carried out by XMM-Newton. Covering an area of 50 deg super(2), the survey contains ~450 galaxy clusters out to a redshift ~2 and to an X-ray flux limit of ~ 5 x 10 super(-15) erg s super(-1) cm super(-2). This paper is part of the first release of XXL results focussed on the bright cluster sample. Aims. We investigate the scaling relation between weak-lensing mass and X-ray temperature for the brightest clusters in XXL. The scaling relation discussed in this article is used to estimate the mass of all 100 clusters in XXL-100-GC. Methods. Based on a subsample of 38 objects that lie within the intersection of the northern XXL field and the publicly available CFHTLenS shear catalog, we derive the weak-lensing mass of each system with careful considerations of the systematics. The clusters lie at 0.1
