|Title||Characterization of a late stage merger: the bright cluster A2319|
|Author||Ms Mariachiara Rossetti|
|Description||One of the most interesting topics in the study of galaxy clusters is their formation and the physical phenomena that occur during cluster mergers. One of the great Chandra discoveries is the existence of two different types of sharp brightness edges: cold fronts and bow-shocks. In A2319, one of the brightest galaxy clusters, Chandra has observed a cold front and shock heated gas in the peripherical regions, indicating that it is probably a late stage merger. We propose an XMM-Newton observation of this cluster, in order to perform a detailed characterization of temperature and metal abundance structure of a late merger. More specifically, we plan to measure the metallicity profile across the cold front and the temperature of the shocked regions.|

|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.
