Protons can be accelerated to very-high-energy by shocks in many astrophysical environments, e.g., gamma-ray bursts (GRBs), AGNs, Supernovae (SNe) etc. High-energy secondaries, including gamma-rays, electrons/positrons, and neutrinos, could arise from the interactions of accelerated protons with either the low-energy radiation field or the gas. Subsequently, the electromagnetic cascade will be initiated by the produced gamma-rays and electrons/positrons in the radiation fields and the magnetic environments. In this talk, I will introduce several astrophysical applications of electromagnetic cascades induced by the secondaries of hadronic processes, especially focusing on our recent works on Ultra-high-energy Cosmic Rays (UHECRs), GRBs, Blazar and SNe. |
