Abstract GT-Clusters accumulate processed and primordial material within theatmospheres held in their deep potential wells. The variation ofmetal content with position in a single cluster is an indicator of thebalance between stellar processing and mass infall. The variation ofthe total metal content of clusters with redshift measures the stellarevolution history of the Universe as a whole, and can provide newcosmological data to test theories of structure formation. XMM isuniquely able to make powerful observations of cluster metallicities,and here we propose EPIC observations of a z = 0.5 cluster to providehigh-quality metallicity measurements at a large look-back time.

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.
