Description Our XMM-Subaru study of 12 clusters confirms that Mgas is a low scatter mass proxy, but the slopes of the mass-observable relations deviate from self-similar predictions, dependent on cluster dynamics. We propose to calibrate biases in the mass proxies based on 3 independent probes (Xray-lensing-velocity dispersion) for a volume-limited sample of 52 luminous clusters, and to investigate the origin of the biases by adding a sample of 15 lower-Lx clusters. We will deliver definitive constraints on systematics for upcoming cluster cosmology surveys. The dataset will be a major asset for programs aiming to measure dark energy as well as programs adding a multi-wavelength focus to studies of cluster physics. High-quality X-ray data exist for 47 clusters, we request 650ks for the remaining 20.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
