| Abstract | Although a good deal of indirect evidence points towards moderate or poor groupsas the environment of low-luminosity (and therefore typical) FRII radiogalaxies, there are almost no direct X-ray observations of the required hot,confining medium. An FRII radio source would have a dramatic effect on the gasin a group, heating and potentially expelling a significant fraction of it, withimportant consequences for our understanding of group evolution. In order tocharacterize the X-ray environments of typical FRII sources, we propose a smallsurvey of the nearest few FRII sources of intermediate size drawn from thewell-studied 3CRR catalogue. Our observations will allow us to detect, andmeasure the properties of, group-scale emission around our targets. |

| 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. |
