Description Wide-angle tail radio galaxies (WATs) have distinctive radio properties and are within rich clusters. Most importantly, our recent work has provided evidence that their relativistic small-scale jets disrupt and decelerate significantly at the ISM-ICM interface. We now propose observations of a small sample of WAT clusters to test this. With these data we will: locate the position of the interface, measure the properties of the medium on either side, and uncover fine structure in the hot gas due to the motion of the galaxies and-or cluster mergers. This investigation will enable us to resolve some outstanding puzzles: what disrupts (terminates and bends) their jets? Are they within cooling flows? Are their clusters merger remnants?

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.
