Abstract | 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 multi-wavelength study of the uniform sample ofoptically-selected clusters based on our X-ray, 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. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
