|Title||An XMM-Newton+HST study of the likely most X-ray luminous z>=0.9 galaxy cluster|
|Author||Dr Tim Schrabback|
|Description||We propose XMM-Newton+HST observations of the new, extremely X-ray luminous cluster ClGJ120959.0+495352 (z=0.90), discovered through our combined search of RASS and SDSS data. Optical and SZ data suggest that it is an excellent candidate for a very massive, dynamically relaxed cooling-core cluster, which are extremely rare at high z. The XMM-Newton data will provide the first resolved X-ray imaging of the system to confirm its dynamical state and constrain both the temperature profile and global cluster properties. The HST data will provide complementary constraints on the cluster mass and dynamical state from strong and weak lensing, enabling the comparison to scaling relations and the assessment if the cluster.s discovery is in line with standard cosmological expectations.|

|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.
