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 ...

Furthermore, the astronomers analyzed multiwavelength data of 3C 216, finding simultaneous flaring activity in optical, ultraviolet, X-ray and ... explain the production of gamma-ray outbursts ...

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

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

These observatories are sensitive to X-ray photons as well ... observed by the EHT and the gamma-ray activity, we can better understand the mechanisms behind the production of the very-high ...

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 ...

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 ...
