Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

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 ...

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 ...

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

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 ...

including high energy (MeV) and low energy (keV) electron beam and X ray irradiation. Comparative studies of gamma, electron beam and X ray irradiation for food and phytosanitary uses are also ...
