The HSC SSP survey constructs an unprecedented shear-selected cluster catalogthrough weak gravitational lensing signals purely tracing dark matterdistribution. We here propose 260 ks X-ray follow-up observations of 9intermediate-redshift (zvirgul0.3) and massive (MWL > 3 x 10^14 h^-1 Msolar )shear-selected clusters discovered in the current HSC SSP survey. By combininghigh quality weak lensing data with the X-ray observations, we aim to extractscaling relations between X-ray observables and weak-lensing mass precisely.XMM-Newton capabilities enable us to perform the first systematic X-ray studyfor shear-selected clusters in an unexplored parameter space.

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.
