Abstract	While AGN & mergers are thought to play important roles in group & clusterevolution, their effects in galaxy groups are poorly understood. We proposeto observe the NGC741 group, which hosts both an old central radio galaxy, & aspectacular infalling head-tail source. Strongly-bent jets, a 100kpc radio trailand intriguing narrow X-ray filaments suggest that NGC 742 is movingtrans-sonically, undergoing stripping and shock heating. NGC 741 possesses bothan old, faint radio lobe & an X-ray cavity, whose inflating plasma may haveunusual properties. We request Chandra and XMM observations of the group withthe goal of examining the roles of the central AGN and infalling galaxy inheating the intra-group medium, & determining the origin of the intriguing X-ray filaments.

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.
