The brightest gamma ray burst has been observed so far in China, which is more than 10 times brighter than the previous one, causing great repercussions in the world.
CTOnews.com, October 16, according to the Institute of High Energy Physics, Chinese Academy of Sciences, 21:17 (Beijing time) on October 9, 2022, the High altitude Cosmic Ray Observatory (LHAASO, Lasso), the High Energy burst Explorer (HEBS) and the discerning Eye Satellite (Insight-HXMT) simultaneously detected the brightest gamma-ray burst to date (GRB 221009A).
The position of ▲ GRB 221009A burst in the LHAASO field of view it is reported that in this observation, LHAASO increased the maximum energy record of gamma-ray bursts by nearly 20 times, and opened a 10-TeV-band gamma-ray burst observation window for the first time in the world. Together with discerning satellite and HEBS observations, it was found that this event was more than 10 times brighter than the brightest gamma-ray ever observed by human beings. These observations break the records of many gamma ray bursts and are of great value for revealing the burst mechanism of gamma ray bursts.
CTOnews.com learned that gamma-ray bursts (Gamma Ray Burst, abbreviated GRB), also known as gamma bursts, are phenomena in which the intensity of gamma rays from a certain direction in the sky suddenly increases in a short period of time and then decreases rapidly.
Gamma bursts were discovered in 1967. For decades, the nature of gamma bursts is not well understood, but it is almost certain that they occur in the explosion process of constant star objects on the cosmological scale. Gamma burst is one of the most active research fields in astronomy. It was named as one of the top ten scientific and technological advances of the year by American Science magazine in 1997 and 1999.
According to Chinanews.com, the discovery of Chinese scientists has caused great international repercussions, a large number of related studies have been carried out rapidly, and a lot of discussions about the possibility of new physics have emerged.
