![]() ![]() If enough material is present, it can form an accretion disk - an incredibly hot structure that feeds material into a black hole and converts this mass into energy, which is emitted as light. Consequently, material that is pulled towards a supermassive black hole can be accelerated almost to the speed of light. With their enormous density and gravitational fields, black holes are some of the most extreme objects in the Universe. This theory was bolstered in 2019, when the Event Horizon Telescope took the first ever photograph of a black hole in the centre of the nearby elliptical galaxy M87, and in 2020, when Reinhard Genzel and Andrea Ghez were awarded the Nobel Prize in Physics for discovering a supermassive black hole at the centre of our own galaxy. ![]() Status: Accepted for publication in the Astrophysical Journal, available on arXivĬurrent theories suggest that most galaxies - if not all - contain a supermassive black hole in their centre, with masses anywhere from millions to billions of times that of our Sun.
