The large-scale structures of extragalactic radio sources are believed tobe determined largely by their environments of hot, X-ray emitting gas. XMMis the first X-ray observatory with sufficient sensitivity to allow a detailedstudy of this interaction. We have selected three nearby twin-jet radio sourcesfrom the 3CRR sample, all of which are known to lie in group-scale hot gasenvironments and which show evidence in their radio structures for stronginteractions with the external medium. XMM observations will allow us to makedetailed maps of the clusters, relating their structure to the radio emission,and to look for the first time for the expected heating of the medium as aresult of expansion work done by the radio source.

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.
