|Title||The origin of ~200 kpc long gas tails in galaxy groups infalling into Abell1367|
|Author||Dr Luca Cortese|
|Description||We propose to use XMM to observe the RSCG42 and FGC1287 galaxy groups in the outskirts of Abell1367. Galaxies in these groups show extraordinarily long HI tails extending for ~160 and 250kpc, respectively, i.e., among the longest HI structures ever observed in groups of galaxies. X-ray data are necessary to determine the physical properties of the hot gas in these galaxies, to look for any hot counterpart of the cold HI tails and to determine the properties of the intra-group gas in these systems. These observations have the potential to discriminate between the competing mechanisms that have been claimed to be responsible for gas stripping in galaxy groups.|

|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.
