Black Hole

The Andromeda galaxy is a barred spiral galaxy 2.5 million light-years from Earth. Otherwise known as Messier 31, it hosts a double nucleus, which is well-explained by a massive disk of apse-aligned stellar orbits about a supermassive black hole, a configuration astronomers call an eccentric nuclear disk. In a new…

The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles' origins remain unexplained. Now, an international research team has proposed a scenario that explains these; black holes with low activity act as major factories of high-energy cosmic particles.…
