Abstract | Wide-angle tail radio galaxies (WATs) have distinctive radio properties and arewithin rich clusters. Most importantly, our recent work has provided evidencethat their relativistic small-scale jets disrupt and decelerate significantly atthe ISM/ICM interface. We now propose observations of a small sample of WATclusters to test this. With these data we will: locate the position of theinterface, measure the properties of the medium on either side, and uncover finestructure in the hot gas due to the motion of the galaxies and/or clustermergers. 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 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. |
