Abstract An XMM/Subaru study of 12 clusters shows that Mgas is an excellent mass proxy,with its scatter <3+/-6%. However the X-ray to weak lensing mass ratio ismorphology dependent, and sensitive to inclusion/exclusion of individualclusters. A complete volume limited sample of 54 clusters with high qualityX-ray and weak-lensing data will deliver the definitive constraints on mass biaswith respect to morphology that are essential for proper control of systematicsin forthcoming X-ray cluster cosmology programs aiming to measure the darkenergy equation of state parameter w, and for any program wishing to add a sharpmulti-wavelength focus to investigations of cluster physics. Archival data existfor 50/54 clusters; we request totaling 110 net ks for 4 clusters.

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.
