Supermassive black holes absorb cosmic matter faster than expected – scientists



Massive black holes located inside galaxies are absorbing cosmic dust and gas disks faster than astronomers expected. This can reduce the time of “feeding” holes from hundreds of years to months, reports Space.com with reference to a study published in The Astrophysical Journal. Using 3D modeling, a group of scientists from Northwestern University in the USA established that black holes, the mass of which is millions of times greater than the mass of the Sun, absorb cosmic matter at the expense of quasars. Quasars are extragalactic objects that, with their brightness, can overshadow the combined light of all the stars in the galaxies around them. 3D simulation.

According to scientists, this is a new method of absorption of matter by black holes, which was discovered by researchers. First, the holes absorb the outer layers of gas and dust, and then the inner ones. When the disk is completely absorbed, the absorption process begins again, the scientists added. Simulations have shown that absorption by a black hole can last only a few months, which is much faster than astronomers had expected. 3D simulation.

Earlier, we reported that NASA showed new pictures of the universe created with the help of several telescopes. Read also: A supermoon was filmed in the sky over Kyiv. PHOTO
