For the first time, scientists discovered the "dormant" black hole outside the galaxy

Xinhua News Agency, Beijing, July 21 (Reporter Zhang Ying) The Southern Observatory recently issued a bulletin saying that a research team composed of multiple national scientists observed a "sleep" black hole without launching high -strength X -ray radiation. This star -rated black hole Located in the Galaxy Galaxy galaxy near the galaxy. Related papers have been published in the British "Nature · Astronomy" magazine recently.

According to the bulletin, when a large -quality star comes to the end of life, it will collapse to form a star -rated black hole under the action of its own gravity. In the two stars that run around the common center, if one of the stars die, a black hole and a glowing companion will form. Scientists mainly detect such black holes in X -ray detection from black holes from the stars. The "dormant" black hole refers to the black hole that does not launch high -strength X -ray radiation. It rarely interacts with the surrounding environment and is particularly difficult to find.

Researchers in the Institute of Astronomical Research of the University of Belgium took 6 years to lead the team to use the "Fiber Fiber Array List Multi -target spectrometer" on the Southern Astronomical Terrace of Europe. Stars, I discovered this "Black Hole Double Star System" named VFTS 243. The system contains a black hole with a mass of at least 9 times the sun and a star with a mass of 25 times the sun.

The research team described this new discovery with the "sea of ​​the sea". The research team believes that the black hole in the VFTS 243 system is the first "sleeping" star black hole to be clearly detected outside the galaxy. The researchers repeatedly questioned and checked the relevant data, and believed that except that there were black holes, other reasonable explanations of the data were not found.

The new discovery helps to understand the formation of black holes deeper. Astronomers believe that when the core collapse of a large -quality star who is about to die, a star -rated black hole is formed. It is still unclear whether the process is accompanied by a violent supernova.

"The stars that form the black hole in the VFTS 243 system seem to be completely collapsed, and there are no signs of previous outbreaks." The author of the paper and the University of Amsterdam, the University of Amsterdam, the scripture script of the University of Amsterdam. He said that the new research provides direct evidence for the "direct collapse" scenario, which is of great significance to explore "the origin of the merger of black holes in the universe."
