Evidence for the Sombrero Galaxy as an Accelerator of the Highest-Energy Cosmic Rays
Hao-Ning He, Eiji Kido, Kai-Kai Duan +12
Ultrahigh-energy cosmic rays (UHECRs) are the highest energy messenger from space, with energies exceeding 1 EeV. Although UHECRs were discovered over 60 years ago, their origin st…
