Current studies on the dynamics of the Intra Cluster Medium are based onspatially resolved, modest spectral resolution CCD data, focused mostly on bulkmotions associated to major mergers. Here we propose a deep XMM observation ofthe cluster Abell 2107, which is so far the only candidate cluster with arotating ICM as found by our group on the basis of shallow Chandra X-ray data.The unique combination of high efficiency RGS and spatially resolved, high S/N,accurately calibrated, EPIC data is the only way to solve the puzzling dynamicalstatus of A2107. In particular, we propose an angle-constrained observation withgrating dispersion along to the rotation axis range to firmly confirm ordisprove the ICM rotation.

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.
