Description The cold fronts found at large distances from the center in A2142 and Perseus changed our understanding of sloshing: not anymore a small disturbance in the core but a cluster-wide phenomenon reaching half of the virial radius. We propose offset observations of four known sloshing clusters, showing the most robust indications of excess surface brightness extending beyond 400 kpc from the center in ROSAT-PSPC observations. We will search for the presence of large scale surface brightness discontinuities, contrary to the predictions of simulations. We will assess if A2142 and Perseus are unique or cold fronts at large radii are a common feature of sloshing clusters. This program will thus provide strong constraints to our understanding of sloshing, ICM micro-physics and cluster mergers.

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.
