Blackbody radiation gamma ray burst
WebApr 10, 2024 · A team of nine astrophysicists led by Vlasios Vasileiou analyzed emission from four bright gamma-ray bursts observed by the Fermi Space Telescope. 17 The team determined that, at a 95% confidence level, there was no violation of Lorentz invariance for energy levels less than 7.6 times the Planck energy, again assuming a linear … WebThis power must drive a highly relativistic outflow of electron-positron plasma and radiation from the source. It is proposed that three gamma-ray bursts, all with identical spectra, detected from B1900 + 14 by Mazets, Golenetskii, and Gur'yan and reported in 1979, were all due to a single event multiply imaged by a gravitational lens.
