Title Metallicity Profile of A2244, the Brightest Cluster Unobserved with XMM-Newton

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

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.
