It took 13 billion years, but the light of the first black holes in the universe finally reaches our telescopes.
And now that we can see the light, we know more about the formation of these distant spatial phenomena, suggests a new study. "In this study, we discovered a totally new mechanism that triggers the formation of massive black holes," said lead author of the study, John Wise, astrophysicist at Georgia Tech, in a statement.
This new mechanism is the rapid growth of dark matter "halos", a mysterious substance that makes up the bulk of the material universe (and which carries this name because it does not absorb or reflect light), according to Space.com .
"Instead of just considering radiation, we have to watch how fast the halos grow," said Wise. "We do not need a lot of physics to understand this – the way dark matter is distributed and the severity that will affect it." To form a gigantic black hole, one must be in a region rare with a convergence of intense matter. "
Wise and his colleagues came to this conclusion after analyzing supercomputer simulations of the evolution of the primitive universe, reported Space.com.
The researchers said that when galaxies form quickly, very massive black holes can form. In these rare galaxies, normal star formation is disrupted and the formation of black holes takes over.
The study also revealed that these massive black holes are far more common in the universe than previously thought, CNN said.
Surprisingly, this light emitted around the first massive black holes in the universe is so intense that it can reach telescopes across the entire expanse of the universe. Incredibly, the light of the most distant black holes has been transmitted to us for over 13 billion light years.
The study was published in the British journal Nature, peer-reviewed.
