High‐Energy Spectral Components in Gamma‐Ray Burst Afterglows
High‐Energy Spectral Components in Gamma‐Ray Burst Afterglows
We investigate two high-energy radiation mechanisms, the proton-synchrotron and the electron inverse Compton emission, and explore their possible signatures in the broadband spectra and in the keV-GeV light curves of gamma-ray burst afterglows. We develop a simple analytical approach, also allowing for the effects of photon-photon pair production, and explore …
