Abstract A number of wakes of enhanced X-ray emission trailing behind galaxies inclusters have now been detected, and theoretical arguments suggest that suchfeatures should be commonplace (if difficult to detect). Wakes offer animportant channel by which gas can be transferred between a galaxy.s ISM andthe surrounding ICM. However, the physical properties of these features remainalmost entirely unexplored. XMM is the first telescope capable of analyzingthe physics of the phenomenon. We therefore propose to make a detailed studyof 3 archetypal wakes. With these data, we will be able to make the firstquantitative comparisons between observations and simulations, and address thebasic issues of the origins and dynamical importance of wakes.

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.
