Astronomers at the Russian Academy of Sciences and Moscow State University have found that the appearance and size of galaxies depended in the remote past for the number of "black hole" embryos found in their fringes, according to the Journal of Cosmology and Astroparticle Physics.
It is believed that in the center of most massive galaxies inhabit supermassive black holes whose mass can equal from one million to billions of masses of the Sun. The reasons for the formation of these objects remain unknown.
Most astronomers now think that supermassive black holes would have appeared in the youth of the Universe from the so-called primordial black holes, an intermediate state between supermacious and conventional black holes, which are also defined as "black hole" embryos.
Astronomer Aleksandr Dolgov of the Institute of Theoretical and Experimental Physics of the Russian Academy of Sciences and his colleague Konstantin Postnov of Moscow State University have discovered that such "embryos" could have played a key role in shaping all Galaxies.
According to the calculations of the scientists, in the first days of the Universe could have appeared a very high number of these stars, about 10-100 times superior to the number of all the existing galaxies.
In addition, Russian astronomers have come to the conclusion that such black holes could have "directed" the rise of galaxies and control their shape and mass, not the other way around, as many astrophysicists now believe.
Based on this idea, the scientists calculated how the shape of the galaxies changed depending on the variation of the spherical accumulations and the mass of the black holes in its center. It was discovered that black holes played the leading role in the birth of elliptical and spiral galaxies, making them form even when the ring of dark matter, which is now considered the main factor of the appearance of galaxies, was absent.
Such a scenario of formation of galaxies may explain, according to experts, one of the greatest cosmological puzzles - because the first galaxies have a very large mass and very heavy black holes, whose existence scientists could not explain before.
