In addition, the group found that the gamma-ray line evolves as a power-law function of time, providing critical clues to unveil the mystery of the line. The study was published in Science China ...

Gamma rays emitted by the decays of radioactive nuclei testify to the production of isotopes through nuclear processes in astrophysical events. We collect measurements of the Galactic γ‐ray sky in ...

Astronomers are trying to understand a mysterious cosmic explosion that the Einstein Probe spacecraft spotted in April last year.

Caption The top panel shows the power-law evolution of the energy of gamma-ray line (blue) detected in GRB 221009A, while the prompt emission (black) and afterglow (gray) of this burst are plotted ...

"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 ...

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

These observations "blur the line between these two types of emission, suggesting that gamma-ray glows often morph into intense pulses", Dwyer explained. Lightning often follows these intense ...

In this research, we will establish an imaging method to visualize line X-ray gamma-rays from activated materials in general. We will expand this method to the fields of space, medicine, and ...

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

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 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 ...
