Discovery of new fast radio burst (FRB) from a cosmic explosion 6 billion years ago

Scientists from Guizhou province in southwest China have discovered for the first time a new fast radio burst (FRB) that likely originated from a cosmic explosion 6 billion years ago. The discovery was made with the help of China’s 500-meter Spherical Radio Telescope (FAST).
Fast radio bursts (FRBs) are super-intense, millisecond bursts of radio waves produced by mysterious and unidentified sources in the distant universe. These extraordinary events generate as much energy in a thousandth of a second as the Sun does in a year. Since 1987, some radio telescopes on Earth have been detecting transient and intense pulses of radio waves coming from deep space.
An astronomical data processing team from Guizhou Province’s Key Laboratory of Information and Computing Science at Guizhou Normal University recently discovered a new FRB and named it FRB 20200317A.
This marked another significant moment when a local research institution in Guizhou discovered an FRB with the help of FAST. The research results were released to their international colleagues via the Astronomer’s Telegram on September 23, 2023.
Astronomers estimated that this mysterious cosmic explosion occurred about 6 billion years ago and was captured by China’s FAST on March 17, 2020.
The observational data come from the FAST Commensal Radio Astronomy FAST Survey (CRAFTS) priority project, led by FAST Principal Scientist Li Di.
The project is the first technology in the world that can simultaneously observe atomic hydrogen gas and pulsars while conducting a simultaneous search for extraterrestrial civilizations.
The Astronomical Data Processing Team performed a systematic processing of data captured by CRAFTS and discovered a new FRB.
Guizhou Normal University and the National Astronomical Observatory, Chinese Academy of Sciences, jointly established a research center in 2014 and a Key Laboratory of Information and Computing Science in Guizhou Normal University by April 2021, which focuses on astronomical big data computation. and processing, have achieved fruitful research results.
