The supermassive black holes They are generally found at a fixed location at the center of galaxies. However, it happens that some of these cosmic monsters tramp in the universe.

Observing and determining the size of supermassive black holes is not impossible, but it is still very difficult. A team of researchers from the Harvard-Smithsonian Center for Astrophysics has relied on a new set of simulations to determine the number of massive gravitational singularities roaming the universe. The study findings may have important implications for understanding the formation and development of supermassive black holes.

The mass of the TNSM (Supermassive Black Hole) is somewhat proportional to the mass of the surrounding galactic bulge. This suggests a link between the developments of the singularity and the galaxy.

Dozens of TNSMs in the Universe

TNSM is a different phenomenon from a simple black hole. The two objects operate according to different logic, and therefore are not born the same way. A stellar-mass black hole forms from the collapse of the core of a massive star. However, the mechanism does not explain the existence of supermassive gravitational singularities that are 55 times the mass of the Sun.

TNSM will be the result of accretion of stars, gas and dust, and mergers with other black holes. This set of processes can be amplified at the level of galactic nuclei, especially in the event of a collision between galaxies. However, the time scale in the universe is very different from our time scale. A galaxy collision can take a long time. This provides a potential window for integration disorder. The process can be delayed or even prevented altogether. Wandering supermassive black holes can arise in this way.

TNSMs are more numerous and brighter

The Romulus Cosmic Simulator at the Harvard-Smithsonian Center for Astrophysics has been called to calculate the number of galactic collisions that may have occurred in the universe. By doing so, the astronomers wanted to know how many TNSMs roaming the universe. ” Galaxies similar in mass to the Milky Way host an average of 12 supermassive black holes, which are typically found on the periphery of the galactic halo and far from the center. ‘,” note the research authors. Note that an article detailing the new study was published in the Journal of Monthly Notices of the Royal Astronomical Society last March.

In the early universe, about two billion years after the Big Bang, Romulus showed that the wandering TNSM was more numerous and brighter than the supermassive black holes at the center of galaxies. This means that massive wandering singularities will produce most of the light we can observe around TNSMs from galactic cores.
