Systematic X-ray study of distant massive clusters discovered by the HSC survey

We propose XMM observations of nine massive clusters of galaxies at 0.8<z<1.1newly discovered by the Subaru HSC survey, aiming at studying scaling relationsand ICM thermal evolution at high redshifts. Since distant, massive clusters arerare, the abundance of such clusters is sensitive to cosmological parameters.With a total exposure of 264 ks, we can accurately determine the ICMtemperatures and luminosities and investigate the gas profiles within r_500.This enables a systematic multiwavelength study of the uniform sample ofopticallyselected clusters based on our Xray, SZE, optical and weak lensingmeasurements, which will have an impact on the forthcoming cosmological studyusing clusters. Owing to its large effective area, XMM is the most suited for this study. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
