This white paper, mostly distilled from a recent study commissioned by the Division of Astrophysics of the American Physical Society, focuses on what very high energy (~100 GeV and above) gamma-ray observations can contribute. Very high energy gamma rays probe the most extreme high energy ...
What causes a gamma-ray burst? The cause of a gamma-ray burst depends on how long it lasts. GRBs that last less than two seconds are caused by the merger of two neutron stars or the merger of a neutron star and a black hole. Longer GRBs, which can last hours, are triggered when...
What is a gamma ray burst? What would be the speed of a wave that has a wavelength of 0.033 m/wave and a frequency of 440 waves/s? What are gamma rays made up of? How fast is light? Explain. How do gamma rays interact with matter?
What is the frequency of gamma rays? What is a gamma ray burst? How are gamma rays detected? What's the difference between x-rays and gamma rays Are gamma rays alpha radiation? How do gamma rays interact with matter? Why are gamma rays dangerous?
A multivariate analysis of gamma-ray burst (GRB) bulk properties is presented to discriminate between distinct classes of GRBs. Several variables represent... S Mukherjee,Eric D.Feigelson,GJ Babu - 《Astrophysical Journal》 被引量: 413发表: 1998年 Unveiling the origin of X-ray flares in Gamma...
An artist's depiction of a gamma-ray burst. (Image credit: NASA, ESA and M. Kornmesser) But it's a puzzle as to just how the big structure came to be. According Horvath, this structure appeared to go against a principle of cosmology, or how the universe formed and evolved. The prin...
Let the Gamma Ray Burst this kind of pen, at will Mang-writing the universe, remove all dissatisfaction and start over. Random Mang-writing in the universe is random Wenmang Action in the universe. This kind of "casually" is the continuous improvement of the planetary civilization of planetary...

Also of note was the lack of gamma rays at the time of the burst, meaning that they are not related phenomena. One star formation that does seem to line up nicely is magnetars or highly polarized pulsars. A new one forms in our galaxy roughly every 1000 years, and hyperflares from thei...
Although evidence and information regarding white holes remain uncertain, a gamma-ray-burst — namedGRB 060614— detected by the Neil Gehrels Swift Observatory in 2006 has been considered as the first recorded occurrence for a white hole.
