Description We propose an 84ks observation of the massive galaxy cluster ClJ1226.9+3332 at z0.89 to detect its emission out to the virial radius (Rv). This cluster is the hottest known at z>0.6 (kT=11.5keV), is highly luminous, and uniquely, appears relaxed. The proposed observation uses the sensitivity of XMM to trace the emission out to Rv, construct a detailed temperature profile, and map surface brightness and temperature variations on small and large scales. Combined with our existing high-quality multi-wavelength data, this will allow us to measure the cluster.s properties (eg total mass, gas-mass fraction) with an unprecedented degree of accuracy. These measurements will enable new cosmological constraints to be placed, and provide the benchmark for comparisons with other high-z clusters.

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.
