Supermassive black hole
Supermassive black hole is a black hole with a mass ranging from millions to billions of times that of the Sun. It is typically located at the center of a galaxy and is associated with energetic accretion processes.
Supermassive black holes are discussed in astrophysics, extragalactic astronomy, and high-energy astronomy.
Status
Supermassive black holes are inferred through observations of stellar motion, gas dynamics, and electromagnetic emission from accretion. Their formation pathways and growth over cosmic time remain active areas of research.
