What would happen to Earth if it were hit by a gamma-ray burst? Gamma-ray expert Q&A Additional resources Bibliography Gamma-ray bursts (GRBs) are the most powerful and violent explosions in the known universe. These brief flashes of high-energy light result from some of the universe...
This space wallpaper shows an unusually bright gamma-ray burst, which produced a jet that emerged at nearly the speed of light. Gamma-ray bursts are the most powerful type of explosions in the universe and typically mark the destruction of a massive star

The X-ray emission after this time fades following a PL function (Figure 5, left). The energy emitted during the prompt phase was 𝐸𝛾,iso=(2.5±0.1)×1053Eγ,iso=(2.5±0.1)×1053 erg [52]. The LAT observations are available up to 180 s, when the burst left the LAT FoV. The...
The meaning of GAMMA RAY is a photon emitted spontaneously by a radioactive substance; also : a photon of higher energy than that of an X-ray.
Hence, our calculation supports the picture that Ep–Lp relation is also satisfied within an individual burst. Fig. 4 Relation between time-resolved spectral peak energy Ep and peak luminosity Lp. Same as Fig. 3, but for a spectral peak energy and peak luminosity computed in five time ...

GAMMA}-RAY BURSTSCOUNTERPARTSWe have analyzed the Ulysses, BATSE, and COMPTEL spectral data from the $\\\gamma$-ray burst of June 22, 1992 (GB 920622). COMPTEL data reveal a hard to soft evolution within the first pulse of the burst, while the mean hardness ratios of the three pulses ...
