|Title||Four Irregular Galaxy Clusters with Multiple Gas Condensations|
|Author||Dr William Forman|
|Description||We propose XMM-Newton observations of four dynamically young clusters with no ongoing major mergers that can be divided into two classes: those with cD galaxies (A1314 and A1589), and those without (A76 and A1913). The proposed observations can map the X-ray emission of the four clusters 10 times better than ROSAT, detect gas condensations (with or without associated galaxies), make temperature maps and determine abundance distributions. With these results, we can better understand the formation of central X-ray halos and their impact on the evolution of young clusters, the distribution of dark matter halos in young clusters, minor mergers, X-ray emission from galaxies in clusters, cluster - galaxy interactions and at least for A1314, the radio - ICM interaction.|

|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.
