A group of astronomers, including some from India, have detected a short and powerful burst of radiation. The burst of high-energy radiation existed for around a second.
NASA’s Fermi Gamma-ray Space Telescope had detected the burst of high energy radiation for the first time in 2020.
According to the data, the death of a massive star was the reason behind the shortest Gamma-Ray Burst. Such events are considered one of the most powerful activities in the universe. They can travel across billions of light-years.
The researchers released the details about the burst named GRB 200826A in two papers, which have been published by Nature Astronomy. While one paper deals with the Gamma-ray data, the second describes the GRB’s multiwavelength afterglow and evolving light of the supernova explosion.
“Such a discovery has helped to resolve the long-standing issues related to gamma-ray bursts. Also, this study triggers to re-analyze all such known events to constrain number densities better,” Dr. Shashi Bhushan Pandey, who was part of the study, said. He is associated with the Aryabhatta Research Institute of Observational Sciences (ARIES).
