Erratic black hole regulates itself

This animation shows how radio jets may be suppressed in the micro- quasar GRS 1915. Material is being pulled from a red companion star into a black hole via a blue, rapidly rotating disk. The animation begins with a jet blowing material away from the black hole. Later, when the disk is heated by powerful radiation from close to the black hole, a wind is driven off the disk. As the wind strengthens, the jet apparently is shut down because the wind deprives the jet of material that would otherwise have fuelled it (c) NASA, CXC, A. Hobart

New results from NASA's Chandra X-ray Observatory have made a major advance in explaining how a special class of black holes may shut off the high-speed jets they produce. These results suggest that these black holes have a mechanism for regulating the rate at which they grow... — full story
