We propose a systematic study to calibrate how various galaxy clusterobservables scale with mass, using precision, HSC-derived, weak lensing massmeasurements and make a stringent test of the assumption of hydrostaticequilibrium of clusters. The exquisite quality of multi-band HSC imaging willenable us to improve both the precision and accuracy of weak-lensing massmeasurements, and allow us to significantly reduce systematic error forindividual cluster mass measurements. By combining these weak lensing massmeasurements wit deep XMM-Newton X-ray and ACTPol Sunyaev-Zel.dovich effectdata, we will have an unprecedented ability to constrain the physical state ofthe intracluster medium. Our project provides an essential bridge to future, cluster-based, cosmological studies by eROSITA.

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.
