Wide-angle tail radio galaxies (WATs) are a challenge to ourunderstanding of the way in which extragalactic radio sources interactwith their environment. Neither the disruption of their jets nor the100-kpc-scale bending of their tails is fully understood. WATs alwaysinhabit X-ray-luminous clusters, and recent cluster merger events maygive rise to observed clumpy X-ray emission and to large-scale winds thatbend and disrupt the jets. We propose to test this model in a smallsample of well-studied WATs. XMM.s high sensitivity and spatialresolution will allow us to determine the nature of the clumpy gas and

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.
