The Auger collaboration, which operates a cosmic ray observatory spanning 3000 km2 (~1158 sq mi) in the Argentine Andes, announces the observation of an unexpected structure in the spectrum ...
Researchers have succeeded in the direct, high-precision measurements of cosmic-ray electron spectrum up to 4.8 TeV, based on observations with the Calorimetric Electron Telescope (CALET).
Galactic cosmic rays (GCRs) are energetic particles traveling across the Galaxy as high-energy beams, and are a unique probe to explore the astrophysical particle accelerators and the interstellar ...
THE shape of the spectrum of cosmic ray electrons in the 100 GeV range and beyond can provide information about a variety of problems in cosmic ray astrophysics. The differential energy spectrum ...
