Abstract We have recently found significant bulk velocities on the order of >2000 km/s inthe ICM of Abell 576, as a result of a systematic search for ICM bulk motions inthe ASCA archive. Such high gas velocities have a profound impact on ourunderstanding of formation and evolution of clusters as well as in determiningfundamental physical characteristics such as ICM mass and energetics. Therefore,independent confirmation of this discovery is crucial. XMM provides a uniqueopportunity to corroborate and improve such measurements due to the excellentgain stability of EPIC-MOS, which allows us to tailor the observationspecifically for velocity studies. This will provide an enormous improvementover previous satellites allowing us to measure gas velocity differences of ~ 400km/s.

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.
