Title Properties of the compression wave in Bi-modal Merging Clusters

Author Dr Jean-Luc SAUVAGEOT
Description The physics of the compression wave forming at the beginning of major cluster mergers is still not well understood because of the lack of X-ray observations of equal mass merging clusters before the maximum core collapse. We propose to observe with XMM-Newton two carefully selected clusters displaying a bi-modal distribution in the optical and X-ray. These data and parallel optical observations will allow for the first time to directly determine the physical conditions (such as density, temperature, gas mixing) in the compressed hot gas and the interplay of the compression waves with the star formation rates of the galaxies.

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.
