They identified those with the presence of what is known as ‘misaligned’ gas – in other words, gas which rotates in a different direction from the stars in the galaxy, signaling a past galaxy interaction. The Southampton scientist, working with researchers at the universities of Copenhagen and California, used data from the 4-meter Anglo-Australian telescope in New South Wales, Australia* to study the orbits of gas and stars in a large sample of more than 3000 galaxies. How SMBHs get enough fuel to sustain their activity and growth still puzzles astronomers, but the work we have carried out provides a step towards understanding this.” Supermassive black holes can make the centers of galaxies shine very brightly when they capture gas and it’s thought this process can be a major influence on the way that galaxies look today. Sandra Raimundo, comments: “Supermassive black holes fuel their activity by, in part, the gradual accumulation of gas from the environment around them. These are known as ‘supermassive black holes’ and exactly how they are formed or gain enough fuel to power themselves is still a mystery.Īstrophysicist and lead researcher from the University of Southampton, Dr. Some black holes are gigantic, with masses millions of times greater than our sun, emitting enormous amounts of energy.
This increases the force of gravity to a point where nothing can escape, not even light – hence the name. ” data-gt-translate-attributes=””>black hole can be created when a star collapses, squeezing matter into a relatively tiny space. Miniature black holes could have a mass smaller than our Sun and supermassive black holes could have a mass equivalent to billions of our Sun. Astronomers classify black holes into three categories by size: miniature, stellar, and supermassive black holes. A black hole is a place in space where the gravitational field is so strong that not even light can escape it.
