Radio Jets Clearing the Way Through a Galaxy: Watching Feedback in Action

Abstract
Pushy Black Hole: The giant black holes that sit at the centers of most galaxies influence the way galaxies evolve in poorly understood ways. Morganti et al. (p. 1082 ; see the Perspective by McNamara ) have acquired high-resolution radio images of a galaxy with an actively accreting black hole from which a jet of relativistic particles emanates. The observations show that a cloud of neutral hydrogen gas is being driven outward, possibly limiting star formation and galaxy growth.
