Both gamma-ray bursts and supernovae have affected life here over the course of its 4-billion-year evolution. Bruce Dorminey, Forbes, 8 Jan. 2025 As reported previously, gamma-ray bursts are extremely high-energy explosions in distant galaxies lasting between mere milliseconds to several hours....
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.
"This event looks unlike anything else we have seen before from a long gamma-ray burst," Rastinejad said in astatement at the time of the discovery. "Itsgamma raysresemble those of bursts produced by the collapse of massive stars. Given that all other confirmed neutron star mergers we have...
Reports on the discovery made by astronomers as of July 2002 about the cause of gamma ray bursts. Detection of a telltale spectrum of a fading supernova near the gamma ray burst GRB 011121; Difficulty faced by astronomers to study gamma ra...
Gamma Ray Bursts (GRBs) are short bursts of gamma rays lasting from a small fraction of a second to a few hundred seconds that are observed from random directions of the sky at a frequency of roughly once per day. A small sample of gamma ray burst light curves is shown in Fig. 19.1...
Explore gamma rays. Learn the definition of a gamma ray and see its characteristics. Find the sources of gamma rays on Earth and outer space, and...
GAMMA-RAYS, BURSTSA simple test for time-asymmetry is devised and carried out on the brightest gamma-ray bursts detected by the Burst and Transient Source Experiment (BATSE) on board the {\\it Compton} Gamma Ray Observatory. We show evidence that individual bursts are time-asymmetric on all ...
Gamma-ray bursts (GRBs) are the most energetic electromagnetic sources in the Universe, releasing 1042–1047 J (refs. 1,2) in prompt gamma-ray radiation. Fifty years after their discovery, the physical origin of this emission is still unknown. Synchrotro
作者: G Bursts 摘要: Gamma-ray bursts are the most luminous explosions in the Universe, and their origin and mechanism are the focus of intense research and debate. More than three decades after their discovery, and after pioneering breakthroughs from space and ground experiments, their study ...
