A new observatory is set to detect sources of cosmic rays, dark matter and other relics of the Big Bang in a few years' time.

Astronomers have detected the most distant very-high-energy blazar ever observed, capturing gamma rays that traveled nearly 8 ...

Gamma rays are among the most powerful types of radiation in nature and a key area of interest in the search for dark matter, especially for scientists who support the WIMP theory. As per their name, ...

For decades, scientists have puzzled over why certain atomic nuclei unexpectedly produce large numbers of low-energy gamma rays. A new experiment traced the effect to magnetic changes inside the ...

Dark matter is known to make up roughly 85% of all mass in the universe, as evidenced by the way galaxies spin and how galaxy ...

Scientists traced a mysterious surge of low-energy gamma rays from zinc-70 to magnetic changes occurring inside its nucleus. The breakthrough could improve models of how stars, supernovae, and neutron ...

In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many ...

The eROSITA telescope has provided astronomers with a groundbreaking X-ray catalogue, unveiling close to two million energetic celestial objects. This extensive release has notably doubled the ...

Prompt Gamma Activation Analysis (PGAA) employs neutron irradiation of a sample to excite atomic nuclei, triggering the emission of characteristic gamma rays within nanoseconds of neutron capture or ...

Cosmic rays are high-energy charged particles, predominantly protons and atomic nuclei, that permeate the Galaxy. As they traverse the interstellar medium, they encounter gas, dust and photon fields, ...
