Title A textbook example of ram-pressure stripping in Hydra A

Description Ram-pressure stripped tails have been observed in a handful of individual interacting galaxies. In an XMM mosaic program targeting the outskirts of the Hydra A cluster, we discovered a spectacular infalling galaxy group with a very long tail (> 400 kpc long) of hot X-ray emitting gas. This system shows a striking similarity with simulated infalling galaxy groups. It provides a unique opportunity to test our understanding of the ram-pressure stripping process and study the virialization of the infalling gas within the main dark-matter halo. We propose a new 200 ks observation of this accreting substructure with XMM

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.
