|Description||The nearby dark group centered on NGC 1407 is notable for a nearby bright galaxy (NGC 1400) with a velocity differing by at least 1200 km-s. This large velocity difference, plus controversy over these two galaxiesa?? respective distances, has led to a wide range of mass estimates for this group. Our analysis of XMM-Newton data reveals an extended region of enhanced surface brightness near NGC 1400 which may be a cold front. We also find that the hottest regions lie between NGC 1400 and 1407, suggesting that their atmospheres are colliding. We propose [.text on Chandra cut .] a 30 ks XMM pointing covering the east side of NGC 1407 to obtain a complete temperature map as well as a total group mass profile.|

|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.
