Highly energetic explosions in the sky are commonly attributed to gamma-ray bursts. We now understand that these bursts ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

These techniques utilize gamma rays to assess the properties of materials ... to accurately measure the thickness of different metal plates, such as aluminum, copper, and steel.

On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, ...

WEST LAFAYETTE, Ind. -- An international team of astronomers has observed extremely rapid bursts of high-energy gamma rays from a distant galaxy, an observation that is challenging how astronomers ...

Normally when people think of gamma rays -- bursts of an incredibly high-energy form of light -- they are coming from out of this world, such as solar flares, exploding stars or black holes ...

Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...

As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is reported in a research paper published on the arXiv preprint server.

This measurement, outlined in a paper published in Physical Review Letters, is the gamma-ray-to-neutron branching ratio in ...

Spectral gamma ray logging is based on the principle that different radioactive elements emit gamma rays with different energy levels. By using a scintillation detector and a multichannel analyzer ...
