Determining the effects of baryonic feedback on galaxy cluster scaling relations

Calibration of scaling relations between weak lensing mass and Xray observablesis a powerful tool for cluster count cosmology. Recent studies show thatenergetics due to feedback from active galaxies and star formation becomessignificant at group and lowmass cluster levels, implying that low mass systemsmight follow a different scaling than massive clusters. Here we propose toextend the Xray coverage of low mass clusters in the CFHTLS field by a factorof approximately 4 in order to measure the effects of feedback on clusterscaling relations. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
