Sagittarius A* It is a massive black hole at the center of the Milky Way Galaxy. It is one of the most amazing things known to man in space. It contains a surprising anomaly discovered by two astrophysicists from the National Autonomous University of Mexico, Gustavo Magallanes-Guijon and Sergio Mendoza.
Scientists were interested in reports of gamma radiation, which had previously been associated with Sagittarius A*. They suspected that there might be some black hole secret hiding there. Their intuition did not disappoint, because They discovered something strange about her.
Guijón and Mendoza analyzed gamma-ray data available from the GLAST space observatory. Analysis of the period from June to December 2022, They observed that a gamma ray burst emanates from the vicinity of the black hole approximately every 76 minutes. It is the brightest source of electromagnetic glow.
Differences in the appearance of these flares are subtle and indicate a pattern in the signals produced. This is very surprising, because black holes do not emit the amount of radiation that we can detect using today’s technology. So what sends out gamma signals?
The regularity of the flares led Mexican astrophysicists to conclude that… Emitted by something orbiting Sagittarius A*. It is likely a cloud of hot gas held in place by the black hole’s strong magnetic field. It also causes particle acceleration, leading to gamma ray bursts.
Interestingly, this is not the first evidence that “something” is orbiting in the region of the Sagittarius A* black hole. It has been proven that radio waves are sent into space approximately every 70 minutes, and X-ray bursts are sent into space every 149 minutes. These discoveries already indicate that a cloud of hot gas is orbiting the black hole. According to the hypothesis of Guijón and Mendoza During its orbit, the cloud emits energetic gamma-ray bursts. As it cools, it glows more strongly in radio light.
Scientists were able to determine this The gas cloud’s orbital distance from Sagittarius A* can be compared to Mercury’s distance from the Sun. However, with an orbital period of more than 70 minutes, it is moving at an incredibly high speed, about 30 percent. The speed of light. Despite these results, the mystery of the flares in the vicinity of one of the most powerful black holes in our galaxy still requires very intensive research.
