Very high energy gamma rays probe the most extreme high energy particle populations in the burst environment, testing models of lepton and proton acceleration in GRBs and constraining the bulk Lorentz factor and opacity of the outflow. Sensitivity improvements of more than an order of magnitude in...
The brightest gamma-ray burst ever seen as observed by the Swift X-Ray Telescope around an hour after it erupted. (Image credit: NASA/Swift/A. Beardmore (University of Leicester)) One of the most remarkable GRBs observed to date is known as the "brightest of all time," or BOAT, GRB....
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...
When was the X-ray generator invented? Which electromagnetic frequencies does EPR spectroscopy use? What is range in nuclear physics? How big is a gamma ray? What is a gamma ray burst? What is electromagnetic radiation? The full range of frequencies of electromagnetic radiation is called ...
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...
Fast radio bursts aren't the only powerful and mysterious energy blasts that puzzle astronomers. Gamma-ray bursts, first discovered in the 1960s, are some of the most powerful emissions in the universe. You can learn more about them onNASA's Hubblesite. The first FRB emerged from the Small...
What technology uses gamma rays? How powerful is a gamma ray burst? What's the difference between x-rays and gamma rays How does time slow down at the speed of light? 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 frequen...
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...
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...
Stage 3: Astronomers develop a model for the thing, find evidence that matches their predictions, and vast majority of the astronomical community comes to a consensus on what this thing is. Like quasars and gamma ray bursts. YouTuber’s make their videos. Textbooks are updated. Balance is re...
