|Title||Study of the chemical enrichment in a massive hot cooling-flow cluster|
|Author||Mr Norbert Werner|
|Description||Clusters of galaxies are excellent laboratories for the study of the nucleosynthesis and chemical enrichment history of the Universe. These studies are currently biased toward relatively cooler (2-4 keV) clusters. However, the enrichment history of the massive hot clusters might be different from that of the smaller and cooler systems. Therefore, we propose to enlarge the sample of clusters observed with the RGS on XMM-Newton with Abell 2029, a hot luminous massive cluster with a cooling core. Despite of the high mass of this system, the cool gas in the core will allow us to measure the abundances of many elements. A deep (130 ks) observation will provide us with EPIC and RGS spectra of excellent statistics, which allows us to accurately measure the abundances O, Ne, Mg, Si, S, Ar, Ca, Fe, and Ni.|

|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.
