Shedding light on the prompt high efficiency paradox - self consistent modeling of GRB afterglows

Paz Beniamini, Lara Nava, Rodolfo Barniol Duran +1

We examine GRBs with both Fermi-LAT and X-ray afterglow data. Assuming that the 100MeV (LAT) emission is radiation from cooled electrons accelerated by external shocks, we show tha…
