Scientists have been working on the theory of radiation from black holes for a long time and now a new study has found that it may be related to the size of the black hole. Researchers at the University of Illinois Urbana-Champaign have discovered black holes that emit flashes of light. This glow is visible when it eats gas and stars, and the change in this brightness is related to its size.
faster than the whole galaxy
Supermassive black holes are hundreds of billions of times more massive than our Sun. Usually these are in the center of the Galaxy. Sagittarius A* is also present in the center of our galaxy Milky Way. When these supermassive black holes are not active, they do not emit much light, but when they are active, the radiation emitted from them is brighter than the galaxy. The glow emanating from them can be observed for a few hours to decades.
Why does the light go out?
Study lead author Colin Burke said, ‘Many studies have linked the light emitted from the supermassive black hole to its mass, but there have never been any confirmed results.’ Such black holes swallow large amounts of matter. When this matter starts moving at a high speed due to its gravity, a large amount of energy is released due to which the nearby matter runs out. This causes the wind to blow in the galaxy. On the basis of this brightness, the size of supermassive black holes and white dwarf stars are expected to be known. They can also detect some of the smaller intermediate-mass black holes, of which only one has been found to date.
