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

| 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. |
