Abstract
We show simulation results of multi-wavelength emission from gamma-ray burst afterglows. Our numerical code can follow the temporal evolution of the electron energy distribution in the forward shock region with injection, radiative cooling, and adiabatic cooling. Our exact treatment can generate the evolutions of synchrotron and SSC spectra. Depending on the CSM density profile, and microscopic parameters, a variety of gamma-ray lightcurves are predicted. Those results can be compared with future observations with MAGIC, H.E.S.S., VERITAS, CTA, HAWC, Alpaca, and LHAASO.
