Located in the center of our Galaxy and before Sagittarius A* (Sgr A*) Every 76 minutes, gamma bursts came to our planet from the aforementioned supermassive black hole. According to a new study, the source of these explosions may not be the black hole itself, but a mass of matter traveling around it at very high speed.

The gas mass around the black hole can be a source of gamma radiation

According to a study on arXiv that has not yet been examined by other researchers, the source of the gamma pulses is not Sgr A*, but a gigantic mass of gas that orbits the black hole at a speed of 100,000 kilometers per second. From the National Autonomous University of Mexico The study by two researchers put forward a new theory about the center of gamma beats, which was first discovered in 2021. The first study stated that the source of these pulses may not be the black hole itself.

Black holes have an event horizon. This beyond the event horizon Not even light can escape the gravity of a black hole. Therefore, it was thought that the gamma radiation did not come from Sgr A*, but from the surrounding structures. Supermassive black holes form an accretion disk as they attract matter around them. Radiation and particle emissions can occur from these accretion disks.

The research used the Fermi Gamma-Ray Telescope

In their study two researchers From the Fermi Gamma-Ray Space Telescope He conducted research based on the data received. Researchers discovered the harmony between X-ray and gamma pulses from the structures surrounding Sgt A*. “The multi-wave periodicity between X-rays and gamma rays indicates the existence of a single physical mechanism that produces them.”me.” he said.

scientists “unique oscillating physical mechanism” By comparing the emission data with the gas cloud, it turned out that the gigantic gas cloud, which he called the gas cloud, was the source of both emissions. This gas cloud revolves around the black hole at a third of the speed of light.

With the new discovery, scientists Structures around black holes will be able to understand better.
