The Shapley Supercluster core hosts a remarkably dense structure showing threegalaxy clusters --A3562 A3558, A3556-- and two galaxy groups --SC1327-312,SC1329-313-- connected to each other by a filament of hot gas and galaxies. Thisproposal aims at completing archive data in order to cover continously thisfilamentary structure. A combined analysis of X-ray data and optical surveyswill enable us to investigate thermodynamics of the ICM overcoming group andcluster interactions in the area, and constrain the influence of galaxy-ICMinteractions in the global budget of the environmental effects affecting galaxyevolution. We will further search for X-ray emission from the hottest anddensest phase of the WHIM, by separating ICM and filament emissions.

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.
