Gamma Ray BurstsMagellanic CloudsDistanceGalactic RadiationHalosSpatial DistributionSeveral lines of evidence (the log N(> S)-log S curve and the spatial distribution of bursts) suggest that gamma-ray bursters may reside in an extended halo population, at distances of about 100 kpc from the Earth...
Cosmic gamma-ray bursts of a duration of about 10 seconds have been detected. Theories concerning the possible causes of the observed bursts are discussed, giving attention to material falling onto a neutron star, very powerful stellar flares, collisions between antimatter and stars, the emission ...
Machine-learning algorithms and observational data have helped astrophysicists identify two distinct classes of kilonova-associated gamma-ray bursts (GRBs), one of the most energetic explosions in the universe1.

The meaning of GAMMA-RAY BURST is a brief, powerful jet of gamma rays detected deep in space that is generated by the collapse and explosion of a celestial object —abbreviation GRB. How to use gamma-ray burst in a sentence.
such as the relation between elves and terrestrialgamma ray bursts. The first TLE-aimed satellite mission ISUAL, though it was forced into decommissioning in 2016 due to a mechanical failure of the host platform, had been providing valuable data for 12years from space. The new generation of sp...
(those with luminosity peak in the 1-30 MeV range) can be unified with GeV blazars (those with luminosity peak at GeV energies) assuming that in GeV blazars the gamma-ray flares are produced via Comptonization of broad emission lines, whereas in the MeV blazars they result from Compton...
华威大学的天文学家发现,需要两颗恒星才能产生伽马射线暴。 新的研究解决了恒星如何足够快地旋转以创造条件将高能物质射流发射到太空的奥秘,并且发现诸如月球和地球之间的潮汐效应就是答案。 这项发现是在《皇家天文学会月报》中报道的,它是使用数千个双星系统的模拟模型做出的,即具有两个彼此围绕运行的恒星的太阳系。
The new joint observations have revealed that the afterglow's inflection point from the slow attenuation to a quick one appeared quite early, signifying that the burst-produced jet is very narrow, one of the narrowest gamma-ray bursts ever detected. ...
