Astronomers using ESA&aposs XMM-Newton X-ray Observatory have discovered that ultra-fast outflows are quite common in active galaxies. About 40 per cent of the sources in their sample show outflows that arise from the vicinity of the central black holes. By estimating the mass and energy released by the outflows, the astronomers have identified them as major agents in the feedback processes required by models of galactic evolution to explain the observed correlation between the mass of black holes and the stellar content of their host galaxies.
