Abstract One of the most interesting topics in the study of galaxy clusters is theirformation and the physical phenomena that occur during cluster mergers. One ofthe great Chandra discoveries is the existence of two different types of sharpbrightness edges: cold fronts and bow-shocks. In A2319, one of the brightestgalaxy clusters, Chandra has observed a cold front and shock heated gas in theperipherical regions, indicating that it is probably a late stage merger. Wepropose an XMM-Newton observation of this cluster, in order to perform adetailed characterization of temperature and metal abundance structure of a latemerger. More specifically, we plan to measure the metallicity profile across thecold front and the temperature of the shocked regions.

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.
