FRII radio galaxies are the most powerful jet-driven AGN outbursts in the localuniverse. Constraints on their hot-gas environments and internal energydensities from X-ray observations suggest that in some cases the energy inputfrom the radio galaxy as it expands is comparable to the binding energy of thehot IGM, so that the radio galaxy should be drastically heating or evenunbinding a large amount of the baryonic matter in its environment. At present,however, there are no observations of nearby FRII radio galaxies in poorenvironments with sufficient sensitivity to observe this process in action. Wepropose detailed observations of 2 objects with a sensitivity that will allow usto observe the effects of FRII energy input on the temperature, density and entropy structure of their host groups.

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.
