The metal abundance profiles in the outskirts of individual galaxy clusters arecurrently mostly unconstrained by observations. These profiles will depend onthe primary enrichment process through cluster galaxies, e.g., ram pressurestripping or galactic super winds. So, measurements can, in principle, constrainwhat the dominant process is. This is the goal of this proposal. We propose ashort supporting XMM-Newton observation of A2244, the brightest cluster in thesky that has not been observed with XMM-Newton until now, to constrain the metalabundance profile out to 0.6 R_180 with a sensational total absolute uncertaintyof Delta Z(0.6 R_180)virgul0.06 solar using our 70 ks Suzaku observation.

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.
