Abstract We propose the intensive observation of the galaxy cluster A1413 to gain thefirst precise observational description of the outskirts of a galaxy cluster inorder to investigate the physics at play in these external regions and toprovide the first X-ray observational constraints on the limit of virializationand thermalization of clusters, on the feedback due to galaxy formation, on thedynamical and thermodynamical states of the accreted material from the cosmicweb. Based on existing XMM-Newton observations, we calculate that the requiredexposure time to achieve the scientific goals of our project is 600 ks. Wetherefore ask for an additional 450 ks to complement the 150 ks awarded in AO6.

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.
