Gamma-ray burst

GRB 221009A also known as Swift J1913.1+1946 was an unusually bright and long-lasting gamma-ray burst (GRB) jointly discovered by the Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope on October 9, 2022. The gamma-ray burst lasted for more than ten hours following detection, and could briefly be observed by amateur astronomers. This is also one of the closest gamma-ray bursts and is among the most energetic and luminous bursts. A once-in-10,000-year event, its high-intensity emissions span 15 orders of magnitude of the electromagnetic spectrum from radio to gamma-rays and consequently offers a rare opportunity for researchers to study it and events like it in detail. Radio signals will likely linger for years to come. GRB 221009A came from the constellation of Sagitta and occurred an estimated 1.9 billion years ago, and is currently at a distance of 2.4 billion light-years away from Earth.

The burst oversaturated the Fermi Gamma-ray Space Telescope, which captured photons whose energies exceeded 100 GeV. The Large High Altitude Air Shower Observatory (LHAASO) in China saw 5,000 high-energy photons. (For comparison, in the entire history of the study of gamma-ray bursts, astronomers have detected only hundreds of these.) Some photons even carried a record 18 TeV of energy, which is more than can be produced at the Large Hadron Collider (LHC) at the European Center for Nuclear Research (CERN). Russia's Carpet-2 facility at the Baksan Neutrino Observatory may have recorded a single 251-TeV photon from this burst. By comparing data collected by different observatories, scientists conclude that this event was 50 to 70 times brighter than the previous record holder. It could help physicists study how matter interacts at relativistic speeds, and potentially physics beyond the Standard Model.

GRB 221009A could be caused by a dying massive star undergoing a supernova, or the birth of a black hole. Some physicists speculate that such exceptionally high-energy photons could come from new physics involving dark matter, axions or decaying sterile neutrinos. However, there is no conclusive evidence this gamma-ray burst was caused by a supernova, nor have any neutrinos from this event been detected. Lightning detectors in India and Germany picked up signs of Earth's ionosphere being perturbed for several hours by the burst, though only mildly, and an enormous influx of electrically charged particles was detected. Some astronomers referred to the burst as the "brightest of all time" or "BOAT", a claim justified by the record of known gamma-ray bursts. The afterglow at X-ray energies was hundreds of times brighter than seen before. GRB-221009A is only the seventh gamma-ray burst with X-ray rings. 20 such rings have been identified.

GRB 221009A was subsequently observed by the Neutron Star Interior Composition Explorer (NICER), the Monitor of All-sky X-ray Image (MAXI), the Imaging X-ray Polarimetry Explorer (IXPE), the International Gamma-ray Astrophysics Laboratory (INTEGRAL), the XMM-Newton space telescope, and many others.
