Jets at work: 3C 386 comma driven outflow or runaway feedbackquestionMark

A key ingredient of structure evolution at late times is the accretion energythat is redistributed into the external medium through radio sources, via poorlyunderstood energyexchange mechanisms. Many sources in group environmentsdisplay prominent beltlike Xray structures that are associated with thecentral narrowing of radio sources between their Xrayfilled lobes. The beltsare not like cluster cavity features, and could either be a driven outflow ofcooler gas from the centre, and a potential barrier to feedback, or displacedgas associated with fuelling the AGN, potentially causing runaway feedback. Wepropose to test which is the case in 3C 386, our best example of a nearbydoublelobed radio source with a prominent Xray belt in a poor environment. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
