The new method of the primary black holes

What is dark matter? How to actually appear supermassive black holes? This old question might answer the primary a black hole. Cosmologists from Leiden and China have identified a new way in which might be born, these hypothetical objects immediately after the Big Bang. Their work was published in Physical Review Letters.

In the quest to understand the Universe, scientists are faced with a big mystery. For example, stars move in galaxies as if they are five times more mass than we see. What comprises this dark matter? There is another mystery: galaxy feed enormous black holes in their cores, weighing in at millions of solar masses. In young galaxies collapsium the stars would not be enough time to grow so much. How did these supermassive black holes, in this case?

Primary black holes: the long-awaited answer?

Cosmologists have proposed a hypothetical solution which could solve one of two mysteries. Primary black holes, which appeared shortly after the Big Bang, have the ability to either stay tiny or gain weight. In the first case, they are suitable for the role of dark matter. In the second case, they can become the seeds for supermassive black holes. Cosmologist don-Gan out of the University of Leiden and his Chinese colleagues Yi-Fu Cai, JI Tone and Sheng-Feng Yan China University painted the new method by which in the time of the Big Bang could be the primary black hole.

After the Big Bang, the universe contained a small density perturbations caused by random quantum fluctuations. They are large enough to form stars and galaxies, but are too small to independently become the primary black holes. Vaughn and his colleagues have identified a new resonance effect, which makes the primary black hole is possible by selectively reinforcing certain perturbations. This leads to the prediction that all of the primary black hole should have approximately the same mass. Narrow peaks in the figure show the range of possible masses as a result of resonance.

“Other payments otherwise increase perturbation, but face challenges,” says Vaughn. “We use resonance during inflation, when the universe grew exponentially just after the Big Bang. Our calculation is simple enough for them to work. In reality, the mechanism may be more complicated, but it’s at least a start.”
