"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...
[gamma-ray] bursts show only that we are at the center of the apparent burst distribution,” and (ii) Woolsey’s 1995 review, wherein he noted =-=[11]-=-, “The observational data show conclusively that the Earth is situated at or very near the center of the gamma-ray burst ...
Gamma decay occurs when there is too much energy in the nucleus of an atom, causing it to emit a gamma ray without changing its charge or mass composition. Artist impression of gamma ray burst. (Image credit: NASA) Gamma-ray therapy Gamma rays are sometimes used to treat cancerous tumors...
Gamma-ray bursts reveal largest structure in the universe is bigger and closer to Earth than we knew: 'The jury is still out on what it all means.' By definition, the universe is everything in existence, so nothing can exist outside it. That said, modern theories such aschaotic inflation...
What is a gamma ray burst? What is the half-life of uranium? What nuclide decays by neutron emission to form helium-4? What is stellar energy in nuclear chemistry? What is the carrier particle of the weak nuclear force? What is the penetrating power of an alpha particle?
Both types of long and short gamma ray bursts involve a stage of a hyper-Eddington accretion of hot and dense plasma torus onto a newly born black hole. The prompt gamma ray emission originates in jets at some distance from this 'central engine' and in most events is rapidly variable, ha...
tance is a factor ∼ 100 larger than that expected (eg. Piran 2005) for internal shocks. The very steep decline of gamma-ray and optical flux at the end of the burst suggests that the source turned-off quickly. The flux decline cannot be faster than the limit pro- ...
