Find the missing link on the black hole
For the first time, researchers have discovered that a strong X-ray pulse is emitted from a giant black hole in a galaxy 500 million light years from Earth.
For the first time, researchers have discovered that a strong X-ray pulse is emitted from a giant black hole in a galaxy 500 million light years from Earth.
This pulse is formed by the gas attracted by the gravity of the black hole at the center of the galaxy REJ1034 + 396.
X-ray pulses are quite common among small black holes, but the Durham study first discovered the activity in a supermassive black hole. Most galaxies include Milk Way, believed to contain supermassive black holes in the central region.
The researchers who published their results in the prestigious scientific journal, Nature, on September 18, said their findings will increase understanding of how gas works before falling into the pit. black as if it eats and grows.
The image that simulates matter falls into a supermassive black hole along with the average type of X-ray cycle from REJ1034 + 396 galaxy.
Astronomers study black holes for decades and the ability to see them is based on the fact that the gas will be extremely hot and emit X-rays before it is completely swallowed and disappeared forever.
Using Europe's XMM-Newton satellite, they found that X-rays were emitted as a common sign from a supermassive black hole. The frequency of the pulse is related to the size of the black hole.
Dr. Marek Gierlinski of Durham University's physics department said: "Such signs are characteristic of the well-known small black holes in our galaxy when gas is pulled from a star. companion star. "
"What is really interesting is that we have now established a chain of light black holes and black holes millions of times more massive than the Sun."
"Scientists have been looking for such signs for the past 20 years and our findings help begin to understand more about the activity around the black hole as they grow."
These scientists also hope that future research will reveal to them why some supermassive black holes have these signs while others do not.
This research is funded by the Council of Science and Technology, the European Space Agency, and the Polish Ministry of Science and Higher Education.
