No gamma-ray bursts from within our own galaxy, the Milky Way, have been observed, [161] and the question of whether one has ever occurred remains unresolved. In light of evolving understanding of gamma-ray bursts and their progenitors, the scientific literature records a growing number of local, past, and future GRB candidates.
GRB 221009A was an extraordinarily bright and very energetic 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 was ten minutes long, [1] but was detectable for more than ten hours following initial detection.
Either a long-duration burst in which the presence of a bright supernova is ruled out, or a short-duration burst with extremely long-lasting gamma-ray emission. GRB 080319B: z = 0.937: Swift: The most (optically) luminous event of any nature observed in the universe to date. By far the brightest optical afterglow of any gamma-ray burst. GRB 080916C
GRB 090423 was a gamma-ray burst (GRB) detected by the Swift Gamma-Ray Burst Mission on April 23, 2009, at 07:55:19 UTC whose afterglow was detected in the infrared and enabled astronomers to determine that its redshift is z = 8.2, making it one of the most distant objects detected at that time with a spectroscopic redshift (GN-z11, discovered ...
GRB 080916C is a gamma-ray burst (GRB) that was recorded on September 16, 2008, in the Carina constellation and detected by NASA's Fermi Gamma-ray Space Telescope. The burst lasted for 23 minutes (1400 s). [1] [2] It is one of the most extreme gamma-ray bursts ever recorded, [3] and was the most energetic gamma-ray burst ever recorded, until ...
GRB 080319B was a gamma-ray burst (GRB) detected by the Swift satellite at 06:12 UTC on March 19, 2008. The burst set a new record for the farthest object that was observable with the naked eye: [2] it had a peak visual apparent magnitude of 5.7 and remained visible to human eyes for approximately 30 seconds. [3]
GRB 190114C was an extreme gamma-ray burst explosion from a galaxy 4.5 billion light years away (z=0.4245; [2] magnitude=15.60est [3]) near the Fornax constellation, [4] [5] [6] that was initially detected in January 2019.
GRB 130427A was a record-setting gamma-ray burst, discovered starting on April 27, 2013. [1] [2] [3] This GRB was associated to SN 2013cq, of which the appearance of optical signal was predicted on May 2, 2013 [4] and detected on May 13, 2013. [5] [6] The Fermi space observatory detected a gamma-ray with an energy of at least 94 billion ...
