Astronomers see evidence of supermassive Black Holes made directly in the early universe

Super-massive black holes (SMBHs) are difficult to explain. This solemn uniformity is believed to be at the center of every big galaxy (our Milky Way has one), but their presence sometimes blocks easy understanding. As long as we know, a black hole becomes formed when the stars get bigger. But that explanation is not consistent with all the evidence.

Stellar fall theory works well to explain most black holes. In that theory, at least five times more than our sun comes out of fuel near the end of its life. Because the outer pressure of the atomic mass of the stars is supported by internal gravity from its own set, when there is something to be done when fuel comes out.

Your hypernoeo passes through a blast, then it breaks itself. What is a black hole left? Astrophysicists think that SMBH starts this way, and other things on the & # 39; food & # 39; By their large size increases. They are packed in size, and sit in the center of their gravity, such as a spider fittings in the center of the web.

The problem with that explanation is that it takes a lot of time to happen.

This artist's impression shows supermassive watches surrounding the Black Hole, which are found in the heart of many galaxies. The black hole is surrounded by dusty torses, and around, with a bright stud of a very hot, unstable material. Often high-speed objects are extracted on the black hole poles, which can expand large spaces in space.

In the universe, scientists have studied SMBH, which is ancient. In March this year astronomers announced the discovery of 83 group of SMBs, which are so ancient that they oppose our understanding. In 2017 astronomers discovered the 800 million solar mass black hole, which was completed only after 690 million years after the Big Bang. They came into existence in the early days of the universe, before their super-broad forms grew.

Most of these SMBHs are billions bigger than Suns. They are on high red shifts, that they must have been made in the first 800 million years after Big Bang. But it does not have enough time for the stars to fall to explain the stars. The question facing astrophysicists is that, how did black holes grow up in such a short time?

A pair of Western University researchers in Ontario thinks they have found it. They have a & # 39; direct fall & # 39; The name is a new theory which explains this wonderful ancient SMBH.

His paper title titled "The Mass Function of SuperSmiley Black Holes in Direct-Palaces Sinio" and is published in The Astrophysical Journal Letters. Shantanu Basu and Arpada Das are the authors. Bassu star design and protoplanetary disc are recognized experts in the early stages of evolution. He is also an astronomical professor at the Western University. There is also the Department of Physics and Astronomy of Das West.

Their direct fall theory states that the ancient super-heavy black holes are very fast in very short periods. Then suddenly, they stopped growing. They developed a new mathematical model to explain the rapidly growing, ancient black holes. They say that the Eddington limit, which is a balance between the star's outer radiative force and the inner gravity force, plays a role.

In this direct fall black hole, Eddington limits the growth of the set of masses, and researchers say that these ancient black holes can also exceed that limit, in which they are called Super-Edington stud. Subsequently, due to the radiation produced by other stars and black holes, their production ceased.

Basu states that there were short periods in supermassive black holes, where they were able to grow rapidly, and at some point in time, due to all the radiation of the universe created by black holes and stars, their production was stalled. Release a press. "It's a straight-down scenario."

"This indirect inspection is evidence that black holes arise from direct-collapse and not from stellar fossils," Basu said.

This new theory provides an effective explanation for a prolific issue in astronomy for a short time. Basu believes that the use of these new results can be done with the future observations of the existence of very large black pores existing in the early period of our universe.
