The most bright gamma-rash burst reveals the cosmic mysteries ever seen

On October 9, 2022, astronomers recorded an extraordinary flash of high-energy light. It is the Gama-ray burst (GRB 221009A), named “Boat” (the most bright of all time), which was the most bright and most energetic cosmic explosion ever. It came from a galaxy, about 2 billion light-year away, and its explosion of gamma rays briefly overwhelmed detectors orbiting satellites. Scientists say that such a powerful GRB is extremely rare-Once-10,000 years of event-and its record-setting nature offers a rare opportunity to study a star and study the physics of these extreme explosions.

Decodes ‘boat’

As paperThe GRB 221009A was first detected by NASA’s Fermi and Swift spacecraft. Its initial, powerful gamma-ray flash blinded detectors worldwide. Its extreme nature immediately marked it by other GRB. Although astronomers originally found the boat as a highly bright flash of high-energy gamma rays, after this flash, many wavelengths of light were across the wavelength after one disappearance, thus allowing non-gama-ray-based telescopes. Study it.

One of the biggest challenges was that the concerned Supernova, SN 2022xivw, was hidden by the talent of GRB and only appears later. This behavior highlights how the huge energy of the burst can temporarily disguise the underlying death of the star, making the total observation challenging.

Insight on GRB

The gamma-ray falls into a black hole as this result from the collapse of the core of a star. The newly constructed black hole povers twin beam off particles at the speed of light, breaking through the stars and the construction of the gamma rays seen. GRB 221009A data fits this model but surprises us. Astronomers employed the James web space telescope to detect supernova burst, but could not detect signs of heavy elements such as gold or platinum in the rubble. Meanwhile, NASA’s Fermi Satellite saw a strange gamma-ray line, which is probably the first infallible identity of electrons colliding with positron (their antimators counterparts) and is destructive in a GRB jet. These clues are helping researchers to refine the GRB, model of stellar collapse, and how heavy elements are forged.
