For the first time, we can combine direct imaging of the near event horizon regions during gamma-ray flares from particle acceleration events and test theories about the flare origins," says Sera ...

along with three of the world’s largest imaging atmospheric Cherenkov telescope arrays: VERITAS, H.E.S.S., and MAGIC. These facilities can detect X-ray photons as well as high-energy gamma rays ...

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

"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 ...

Cosmic rays below 100 MeV are key to the origin of life and the evolution of stars, and they activate interstellar matter to emit spectral emission lines of X-rays and gamma rays specific to the ...

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

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.

Most nuclear medicine technologists are employed in hospital settings, where they contribute to the diagnosis and treatment.

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 ...

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 ...
