GT- The redshift of the cluster WARPJ0152.7-1357 is z=0.831, one of the highestknown. This cluster has a high luminosity of 8e44 erg/s (0.5-2 keV) and has twoX-ray components, both at the same redshift, and separated by 1.5 arcmin (700kpc) - probably the result of a merger. The X-ray temperature of this clusterwill be measured as part of an effort to constrain the temperature evolution ofclusters.

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.
