Detected in 2021, the Amaterasu particle ranks among the most energetic cosmic rays ever observed, carrying an estimated 244 ...

Francesca Capel and Nadine Bourriche analyze the most energetic particle that has ever hit Earth and its possible origin in ...

The study of cosmic ray anisotropy and magnetic fields lies at the intersection of astrophysics and plasma physics, revealing subtle imprints of the turbulent interstellar medium and the local ...

New analysis by Francesca Capel and Nadine Bourriche narrows possible sources of the Amaterasu cosmic ray, suggesting nearby galaxies like M82 rather than the Local Void.

Much of our understanding of the Universe and its mysterious phenomena is based on theoretical interpretations. In order to deepen the understanding of distant objects and energetic phenomena, ...

Neutrinos are subatomic particles with no charge and very little mass that are known to weakly interact with other matter in the universe. Due to their weak interactions with other particles, these ...

High energy astrophysics probes the most energetic phenomena in the Universe, from explosive supernova remnants to the powerful outflows near compact objects. A central focus of this field is the ...

The origin of lithium (Li), the third element of the periodic table, has long been shrouded in mystery. This element, commonly found in cosmic rays as two stable isotopes, 6 Li and 7 Li, is crucial to ...

New findings published this week in Physical Review Letters, Measurement of the Iron Spectrum in Cosmic Rays from 10??GeV/n to 2.0??TeV/n with the Calorimetric Electron Telescope on the International ...

Two articles describe how ground-breaking image reconstruction and analysis algorithms developed for surface-based MicroBooNE detector filter out cosmic ray tracks to pinpoint elusive neutrino ...

The latest observations from Low Earth Orbit with the International Space Station provide further evidence of spectral hardening and softening of cosmic ray particles. The CALorimetric Electron ...
