Observational study reports abundant gamma-like air-showers from cosmic rays near the Sun, suggesting novel detection methods with LHAASO.
Cosmic rays with energies of tens of TeV and above, skimming the Sun, could fragment into pions. The resulting gamma photons and muons, as well as subsequent electron pairs, will reach us in the form of gamma or electromagnetic air-showers, gamma-like air-showers on Earth. Their multiple presence may soon be observed and disentangled by the LHAASO telescope array
