Description GT-We propose to make XMM observations of one of the peaks of overdensity in QSOs at z sim 1.1 discovered by Crampton et al. 1989. The concentration has a typical scale of a supercluster and there is evidence for overdensity of faint galaxies in optical and NIR images around some of the member QSOs. The primary purpose is to search for extended X-ray emission from clusters around these QSOs and other clusters associated with this putative supercluster.

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.
