Description Sloshing cold fronts observed at intermediate radii of galaxy clusters carry essential information on the macro-scale dynamical history and the micro-scale cluster physics. Previous Suzaku studies of the nearest cluster, Virgo, revealed two promising cold fronts at radii of 200-300 kpc to the south and west of M87 with pronounced temperature and density discontinuities. We propose three XMM-Newton EPIC observations to map the entire underlying sloshing front and to characterize its properties to a significantly better accuracy than was achieved with Susaku. The proposed study will allow us to test the suppression of fluid instabilities in the intracluster medium and to probe the evolution of the sloshing cold front over the past few billion years in this dynamically young cluster.

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.
