Black holes are giants in the universe. It is generally believed that there are supermassive black holes in the center of all galaxies, and the supermassive black holes in the center of the Milky Way are about 4 million times the mass of the sun. According to the theory, the mass of the black hole in the center of the galaxy can be as high as 654.38+000 billion times that of the sun. However, we don't know how they get such a large mass, especially those black holes that are entrenched in relatively young galaxies (only a few hundred million years).
Astronomers believe that if a black hole hundreds of thousands of times the mass of the sun can exist as a "seed player" of a bigger black hole, then this problem may be solved. Unfortunately, such a medium-mass black hole has been "avoiding" human tracking for a long time. Why there is no such medium-mass black hole in the universe is also an unsolved mystery. Only a small number of "candidates" can be identified at present.
This time, a team of astronomers from Keio University in Chile used the Atacama MMW/MMW array telescope with high sensitivity and resolution to observe the molecular gas cloud 60 parsec away from the center of the Milky Way. Through computer simulation, they concluded that the movement pattern of gas in this cloud can only be influenced by medium-mass black holes hidden in the gas. The research team also found that the movement pattern of this gas cloud is like a "small-scale version" of the supermassive black hole at rest in the center of the Milky Way.
The team's researchers said that the next step will focus on monitoring this black hole to confirm its nature, and use the same technology to find more medium-quality black holes.
Humans are really too small for the universe. Let's explore slowly!
