Description Major mergers of clusters of galaxies are the most energetic events in the present Universe. We propose XMM observations of 5 merging clusters to detect shocks in the intracluster gas. We will use these shocks to determine the global dynamics and local physics of the intracluster medium. Shock physics will determine: (a) if the kinetic energy is effectively thermalized in shocks or if much of the shock energy goes into turbulence, magnetic fields, or cosmic rays; (b) if electrons undergo collisionless heating in the shocks; (c) whether the acceleration of relativistic electrons is effective in these shocks; (d) how angular momentum affects mergers; and (e) what the persistence of small cooling cores tells us about the dynamics of mergers and peaks in

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.
