Was a powerful cosmic explosion seen by the Einstein Probe launched by a supermassive black hole snacking on a star, by a ...

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 ...

"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 ...

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

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 ...

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 ...

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 ...

The use of different diagnostic imaging techniques that employ various forms of radiation such as X-rays (CT and radiography) and gamma rays (PET and SPECT) has revolutionized the management of cancer ...

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 ...

For more information on this research area, see the following pages: I develop gamma ray imaging instrumentation for various applications. Data processing and analysis techniques, including image ...

The highly energetic explosion was initially attributed to a burst of gamma rays emitted either by the collision of two neutron stars or from the death of a massive star. Soon, however ...
