This radiation received its name — gamma-rays — simply because gamma is the third letter in the Greek alphabet after alpha and beta. Unbeknownst to Villard and his cohorts in the early 1900s ...

New research led by the University of Osaka reports the multi-sensor detection of an intense gamma-ray flash that occurred ...

A groundbreaking study from the University of Osaka reveals that lightning produces intense gamma-ray radiation bursts, known as terrestrial gamma-ray flashes (TGFs). Once thought to occur only ...

O'Connor, who specializes in the study of massive cosmic explosions, explained that gamma-ray radiation associated with GRBs is produced by a collimated jet of material moving at nearly the speed ...

This first-of-its-kind observation may help explain an origin of some of the most energetic radiation on Earth. Researchers have for years linked the production of gamma rays to the acceleration ...

Graphic: NASA’s Goddard Space Flight Center and Adam Goldstein (USRA) In the standard model of gamma-ray burst afterglows, “afterglow radiation originates from the collision of the rapidly ...

We’re used to hearing about the sun’s ultraviolet radiation, which we protect ourselves against with sunscreen. The sun also emits much more powerful gamma rays, which are the most energetic ...

Gamma rays are weightless, high-energy packets of electromagnetic radiation — the same stuff that makes up light. However, while visible light can comfortably light up a room, gamma rays can penetrate ...

The research on gamma-ray bursts, including a central engine, magnetized dynamics of plasmas, and radiation, is one of the hot topics in the high-energy astrophysical research. The so-called ...

gamma rays burst from supernova explosions as well as the hottest and most energy dense objects in the cosmos, like pulsars, those highly magnetized neutron stars that emit pulses of radiation.

Gamma radiation is produced as well, in bursts called terrestrial gamma-ray flashes (TGFs), which can last up to 100 microseconds, followed by longer afterglows. Existing data seemed to suggest ...
