| Abstract | We propose a legacy class observation of 11 groups and clusters of galaxies witha total exposure time of 1590 ks to study the enrichment history in a largesample of 29 clusters and groups. This sample will be a definitive sample,because it comprises all nearby clusters that can be observed successfully withRGS. Using the combined power of RGS and EPIC, we will put constraints on theSNIa explosion mechanism, SNcc models and the IMF in the cluster core regionsthrough accurate abundance measurements of 10 elements. The deep EPIC data willallow us to map the spatial distribution of iron, and in some cases silicon, todetermine the enrichment mechanism operating in the Intra-Cluster Medium. |

| 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. |
