|Title||Tales of tails: the Virgo episodes|
|Author||Dr Ming Sun|
|Description||X-ray tails of late-type cluster galaxies were only detected recently with Chandra and XMM. Detailed studies of these systems allow better understanding for ram-pressure stripping, galaxy transformation in clusters, mixing of the stripped cold ISM with the hot ICM, r^ant micro-physics and intracluster SF. However, X-ray tails are rare in blind searches, often submerged in strong cluster background. We propose a targeted search for X-ray tails for a sample of late- type galaxies with known HI tails in the closest cluster, the Virgo cluster. The XMM data, in combination with our large CFHT project for a Virgo Ha survey, will explore the X-ray-Ha correlation in poor environment and put strong constraints on the properties of X-ray tails even if none are detected.|

|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.
