The mass of the central black hole is estimated to be about 4 million times that of the sun.
A black hole can be described as a region of spacetime where gravity is so strong that nothing, including electromagnetic waves, has sufficient energy to escape it.
The theory of general relativity estimates that a compact mass can deform spacetime to create a black hole. The boundary of no escape is known as the event horizon.
The black hole acts like an ideal black body because it reflects no light. Moreover, quantum field theory predicts that event horizons release Hawking radiation, with a similar spectrum as a black body of a temperature inversely proportional to its mass.
Supermassive black holes of millions of solar masses may be created by absorbing stars and merging with other black holes.
