CTOnews.com, December 10, according to the National Space Science Center, on the occasion of the second anniversary of the launch of the Huairou-1 satellite, the National Space Science Center of the Chinese Academy of Sciences, the Institute of High Energy Physics of the Chinese Academy of Sciences, the National Space Science data Center and the National High Energy Physics Science data Center jointly released the first scientific data of the Huairou-1 satellite. The data released this time include the detailed observation data of the first batch of 75 gamma ray bursts, which will help astronomers at home and abroad to carry out "multi-band, multi-messenger" joint observation and research of gamma ray bursts. This is an important step for the "Huairou-1" satellite to provide scientific research services to scientists all over the world after issuing astronomical warning information in real time.

Huairou-1 satellite is called gravitational wave storm high-energy electromagnetic counterpart all-sky monitor, referred to as "GECAM", which mainly detects the bursts of high-energy celestial bodies such as gamma-ray bursts accompanied by gravitational waves. Gamma-ray bursts are the most violent celestial bursts in the universe, and the energy released in just a few seconds is equal to the total energy radiated by the sun in its 10 billion-year life. It is generally believed that the merging of two neutron stars can produce both gamma ray bursts and gravitational waves, which is the core scientific goal of Huairou-1 satellite. In addition, CTOnews.com learned that Huairou-1 can also detect high-energy counterparts of rapid radio bursts, magnetar bursts, X-ray binaries, solar flares and gamma flashes on Earth.

As of November 2022, more than 1600 explosive phenomena of various kinds have been triggered in orbit, including more than 100 gamma ray bursts, magnetar bursts, solar bursts and earth gamma flash, 91 observation notices have been publicly issued, and more than 600 observation warnings have been issued. and repeatedly guide domestic and foreign satellites and ground observation equipment to carry out follow-up observation and joint observation. On October 9, 2022, as an expansion mission of the Huairou-1 satellite, the brightest gamma-ray burst was detected by the high-energy burst explorer payload (GECAM-C) carried on the new technology test satellite in space, and the second high-energy counterpart of a rapid radio burst was detected jointly with the Huairou-1 satellite 02 (GECAM-B) on October 14. The above results have aroused strong repercussions at home and abroad.

According to the satellite operation and data policy, a total of 75 gamma ray bursts were detected by the Huairou-1 satellite from January 2021 to May 2022. Based on the advantages of "Huairou-1" in high time resolution and wide energy range of the detector, "Huairou-1" satellite science application system has designed innovative data products, which is conducive to the identification and study of all kinds of outbreak phenomena. In addition, the scientific application system has also developed a special data analysis tool (GECAMTools), which is released at the same time as scientific data to facilitate the processing and analysis of data by scientific users.

The Huairou-1 satellite is the first opportunistic space science project specially deployed and launched by the Space Science (Phase II) of the Chinese Academy of Sciences.
