• Disclosed the reason for the appearance of giant black holes

  • An international group of astrophysicists from the USA, Finland and the UK explained the appearance of giant black holes whose mass is millions to billions of solar masses. Scientists have shown that they can be formed inside protogalactic in a cessation of star formation.

    An international group of astrophysicists from the USA, Finland and the UK explained the appearance of giant black holes whose mass is millions to billions of solar masses. Scientists have shown that they can be formed inside protogalactic in a cessation of star formation. Article researchers published in the journal Nature Astronomy.

    According to the results of computer simulation for the emergence and growth of supermassive black holes requires that the protogalaxy was a shortage of molecular hydrogen (H2). The latter is a matter for the formation of stars, which could drag the matter for themselves. The researchers found that a sufficient amount of radiation of the Lyman-Werner from neighboring galaxies can trigger the collapse of the N2.

    Emission of Lyman-Werner consists of photons that have sufficient energy to absorbed.2 collapsed with the formation of atomic hydrogen. The calculations showed that these photons can be formed in galaxies with a flash of star formation. This active galaxy must be at a suitable distance from protogalactic. In addition, the bombardment of photons must occur before you begin the process of compression of interstellar gas, leading to the emergence of black holes.

    Astronomers using the hydrodynamic model, calculated that the distance between a galaxy with a flash of star formation and protogalaxies should be 200-300 parsecs, and the difference in their age was less than four million years.
