The cause of the high-energy gamma pulses coming from the center of the Milky Way may not be the supermassive black hole at the center of our galaxy, but a mass of matter orbiting it at a speed of 100 thousand kilometers per second.
Located at the center of our galaxy and previously Sagittarius A* (Sgr A*) Gamma bursts were coming to our planet every 76 minutes from the supermassive black hole named. 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.
Mass of gas around black hole may be source of gamma rays
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 giant mass of gas orbiting the black hole at a speed of 100 thousand kilometers per second. From the National Autonomous University of Mexico In the study conducted by two researchers, a new theory was put forward about the center of gamma beats, which was first discovered in 2021. In the first study, it was 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 Even light cannot escape the gravitational pull of a black hole. Therefore, it was thought that the gamma radiation came not from Sgr A* but from the surrounding structures. Supermassive black holes form an accretion disk as they attract matter around them. Radiation and particle ejection can occur from these accretion disks.
Fermi Gamma-Ray Telescope was used in the study
In their studies, two researchers From the Fermi Gamma-Ray Space Telescope He made investigations using the data received. Researchers detected the harmony between X-ray and gamma pulses of the structures around Sgt A*. “The multiwave periodicity between x-rays and gamma rays indicates the existence of a single physical mechanism that produces them.”i.” he said.
scientists “unique oscillatory physical mechanism” It was revealed by comparing the emission data with the gas cloud that the giant gas cloud, which he described as the gas cloud, was the source of both emissions. This gas cloud orbits the black hole at one-third the speed of light.
With the new discovery, scientists Structures around black holes will be able to understand better.
