| Abstract | Radio galaxies take a variety of morphology. One particularly interesting classis the bent radio source as it probes the environment and provide constraints onproperties of ambient medium and dynamics. Future radio surveys will detectmillions of bent radio sources, unleashing its great potential to study ICM/IGMand dynamics. On the other hand, it is still unclear whether all bent radiogalaxies are associated with groups and clusters. In this proposal, we focus onnearby (z<0.04) NATs to test the simple hypothesis that all NATs are in groupsor clusters. A sample of NATs not in known groups/clusters are selected for XMMobservations. For their proximity, they present best chances to invalidate thehypothesis, which would have important implications for the formation of NATs. |

| 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. |
