Abstract | It has been found with ASCA that both type II and Ia upernovae significantlycontribute to metals in hot intracluster medium, based on the Si to Fe abundanceratio. In order to improve our understanding of relative contribution of bothsupernovae to the ICM, more accurate measurements of not only Fe but also otherelemental abundances are necessary. However, such measurements is limited torich clusters. Here we propose to observe a nearby bright poor cluster A3581 inorder to measure abundance pattern of the overall ICM for O, Mg, Si, S, and Fe.Furthermore, we can study the ICM enrichment processes by deriving a large-scaleabundance gradient of not only Fe but also Si for the first 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. |
