| Description | We propose offset pointings of two intermediate ( M_{500} =1.5 - 3.5 times 10^{14} {rm M}_odot ) mass clusters, MKW3s and A2589, to derive metal abundances up to 0.9 R_{500} and 0.7 R_{500} , respectively, a challenging distance for systems with these masses. By combining X-ray data with optical data we will derive the iron-yields for these systems and compare them with expected iron yields from supernova rates. Since intermediate mass clusters represent a bridge between galaxy groups and massive galaxy clusters, this study will help to solve the conundrum of the different behavior of galaxy groups, which seem to match expected values from supernovae, and massive clusters, which feature a discrepancy by a factor 3-7 . |

| 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. |
