Widespread winds and eedback from supermassive black holes
Keele, UK (SPX) Feb 24, 2015
Astronomers have discovered that the winds from supermassive black holes at the centre of galaxies blow outward in all directions, a suspected phenomenon that had been difficult to prove before now. These new findings, by an international team of astrophysicists, were made possible by simultaneous observations of the luminous quasar PDS 456 with ESA's XMM-Newton and NASA's NuSTAR X-ray telescopes, and support the picture of black holes having a significant impact on star formation in their host ga ... read more
