Description We have recently found evidence of supersonic bulk velocities in the ICM of A576 &- A376. The dependence of these measurements on the gain stability of the spectrometers makes the confirmation of these results crucial. Such high gas velocities have a strong impact on our understanding of formation and evolution of clusters and also in determining basic physical characteristics such as gravitating mass and energetics. Given the high magnitude of the velocity gradient and its spatial extent, XMM provides a unique opportunity to corroborate and improve such measurements. The excellent gain stability of EPIC-MOS will allows us to tailor the observation for velocity studies reducing individual velocity errors to virgul 400--800 km-s, with relatively short exposures.

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.
