Thanks to computer simulations of the universe, scientists have recently discovered the origin of black holes located at the centers of galaxies.
According to Live Science, using the simulation, the research team from the Harvard-Smithsonian Center for Astrophysics created a black hole with a mass 300 billion times that of our Sun.
The above simulation was carried out to find the origin of black holes located at the centers of galaxies and whose mass is 10 billion times that of the Sun. In addition to known super black holes, scientists sometimes discover super black holes whose mass far exceeds what humans can imagine. They are often called heaviest object in the universe.

A typical example is that in 2019, scientists first observed the phenomenon of three galaxies colliding, placing super black holes at their centers in orbits to merge. The collision occurred nearly a billion light years from Earth, in star system SDSS J084905.51+111447.2. To observe this phenomenon, astronomy researchers must use both ground-based and space telescopes.
Using a high-resolution universe simulation called ASTRID, the Harvard-Smithsonian research team modeled the evolution of the universe as it appeared about 11 billion years ago. In the simulation, the team witnessed the birth of an extremely massive black hole following the merger of three galaxies. Each of these galaxies contains its own quasar, a supermassive black hole that sucks in matter and emits intense radiation that can outshine all the stars in their host galaxies combined.
When the trio of quasars meet, they form an even larger black hole and start the process of sucking in matter. “madness” allowing the combined object to reach a supermassive state.
“We discovered a very rare system containing a trio of quasars at cosmic noon, about 11 billion years before supermassive galaxies and black holes reached peak activity.”said Dr. Yueying Ni, head of the research team.
“This system consists of three quasars powered by supermassive black holes, each of which has a mass 10 times that of our own galaxy, the Milky Way.”he added.

Supercomputer simulations show that three galaxies with supermassive black holes at their centers have merged into a single galaxy with a “supermassive” black hole at its center.
The research team’s simulation shows that the trio of quasars had a merger process that lasted 150 million years and formed the most massive black hole in the entire simulation, with a mass greater than 300 billion times the mass of the Sun, even greater than all. the stars of the Milky Way combined.
Still according to Mr. Yueying Ni, the combination of a system of three quasars and the collision of three galaxies is extremely rare. This explains why scientists were unable to detect them or observe the formation of super black holes following such an event.
The Harvard-Smithsonian group’s research was published in the November 30, 2022 issue of the Astrophysical Journal.
