|Title||Jets at work: 3C 386, driven outflow or runaway feedback?|
|Author||Prof Diana Worrall|
|Description||A key ingredient of structure evolution at late times is the accretion energy that is redistributed into the external medium through radio sources, via poorly understood energy-exchange mechanisms. Many sources in group environments display prominent belt-like X-ray structures that are associated with the central narrowing of radio sources between their X-ray-filled lobes. The belts are not like cluster cavity features, and could either be a driven outflow of cooler gas from the centre, and a potential barrier to feedback, or displaced gas associated with fuelling the AGN, potentially causing runaway feedback. We propose to test which is the case in 3C 386, our best example of a nearby double-lobed radio source with a prominent X-ray belt in a poor environment.|

|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.
