| Abstract | We propose to obtain detailed X-ray data for an optically-selected superclusterat z = 0.9. This large scale structure contains at least seven massive clusters,most of which are known X-ray emitters. These observations will allow us toplace accurate constraints on the temperature, surface-brightness profile, andmass fraction of the intracluster medium in the member clusters. The clustersare extremely well-studied in the optical; thus, the addition of XMM data willenable us to study the small-scale relation between the galaxies and gas, toquantify the variation between the X-ray/optical properties of clusters at afixed epoch, and to explore a large scale system of clusters in the process offormation. |

| 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. |
