Description Detailed measurements out to large radii have the potential of improving our knowledge of the metal enrichment in galaxy groups and clusters, by directly exploring most of the systems volume. While in recent years metallicity measurements out to R500 have been done for a sizable number of galaxy clusters, we are still missing systematic measurements at such radii for galaxy groups. We propose to observe a pilot sample of 4 galaxy groups to derive the abundance profiles out to R500. The requested observations will allow us to investigate whether or not the lower metallicity observed for galaxy groups within 0.7R500 persists at large radii or if the missing metals have been ejected to the outer regions.

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.
