Gamma rays are a form of electromagnetic radiation. ... infrared radiation, ultraviolet radiation, X-rays and microwaves. ... according to Einstein's famous equation E=mc^2, ...

Platzman's and Mills' gamma-ray laser proposal involves generating coherent emission of these 511 keV photons by persuading a large number of Ps atoms to commit suicide at the same time, thus ...

Sources emitting gamma radiation with photon energies between 100 GeV and 100 TeV are called very-high energy (VHE) gamma-ray sources, while those with photon energies above 0.1 PeV are known as ...

Gamma rays are high-energy photons produced by some of the most violent events in the universe. We explore this powerful radiation in more detail here.

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.

Prior to these new results, a phenomenon known as curvature radiation was the leading explanation for the Crab’s pulsed gamma-ray emission. Curvature radiation is produced when a high-energy charged ...

Dynamic Gamma-Ray Emissions in Tropical Thunderclouds. In another study presented in this edition of Nature, Marisaldi et al. [2024] ...

Please join us for a virtual seminar "Developing a theoretical model for the gamma-ray emission from the Sun" by Eleonora Puzzoni on Thursday, April 27 at 11 a.m. Abstract: Despite its very close ...

The new study shows that just one of these terrestrial gamma ray flashes, or TGFs, can equal the radiation dosage of about 400 chest x-rays—creating potential hazards for frequent flyers.
