Web28 de sept. de 2016 · Once this transition occurs, the black-hole feeding is suppressed, preventing the SMBH from growing any larger. The authors show that the critical mass for this transition is 1–6 x 1010solar masses — consistent with the maximum masses that we’ve observed for SMBHs in the wild. Supermassive black holes are classically defined as black holes with a mass above 100,000 (10 ) solar masses (M☉); some have masses of several billion M☉. Supermassive black holes have physical properties that clearly distinguish them from lower-mass classifications. First, the tidal forces in the vicinity of the … Ver más A supermassive black hole (SMBH or sometimes SBH) is the largest type of black hole, with its mass being on the order of hundreds of thousands, or millions to billions of times the mass of the Sun (M☉). Black holes are a … Ver más The origin of supermassive black holes remains an active field of research.
