Astronomers discovered eight buried dual AGN candidates, the largest sample of hidden accreting supermassive black holes in late stage galaxy mergers, selected using NASA’s Wide-Field Infrared Survey Explorer (WISE) space telescope. This result will be presented by graduate student Ryan Pfeifle of George Mason University (Fairfax, Virginia, U.S.) at the annual meeting of the European Astronomical Society (EWASS2019) in Lyon, France,…

Magnetic field may be keeping Milky Way’s black hole quiet
Supermassive black holes exist at the center of most galaxies, and our Milky Way is no exception. But many other galaxies have highly active black holes, meaning a lot of material is falling into them, emitting high-energy radiation in this “feeding” process. The Milky Way’s central black hole, on the other hand, is relatively quiet. New observations from NASA’s Stratospheric Observatory…
Astronomers determine mass of small black hole at center of nearby galaxy
If astronomers want to learn about how supermassive black holes form, they have to start small—really small, astronomically speaking. Source: https://phys.org/news/2019-06-astronomers-mass-small-black-hole.html…
Detection of powerful winds driven by a supermassive black hole from La Palma
The supermassive black holes in the centres of many galaxies seem to have a major influence on their evolution. This happens during a phase in which the black hole is consuming the material of the galaxy in which it resides at a very high rate, growing in mass as it does so. During this phase, the galaxy has an active galactic…
