Very High Energy Afterglow of Structured Jets: GW 170817 and Prospects for Future Detections
Clément Pellouin, Frédéric Daigne
We present a complete numerical model of the afterglow of a laterally structured relativistic ejecta from the radio to very high energies (VHE). This includes a self-consistent cal…
