We propose a 70 ks XMM-Newton observation of the hot gas around the unusualradio galaxy IC 4296 (PKS 1333-33) to measure the thermodynamic parameters ofthe hot gas environment. This massive elliptical galaxy lies at the center of anearby group, and has a variety of unusual features suggesting a stronginteraction between the jet and the ambient gas. On 100-kpc scales, the jetsterminate in a mildly edge-brightened radio lobes without a conspicuous hotspot, suggestive of efficient subsonic thermalization of the jet flow. Strongexternal shocks have been found in systems with similar morphologies (e.g.Centaurus A). Understanding the role of AGN feedback has important implicationsto our fundamental knowledge of galaxy evolution.

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.
