An anisotropic minijets model for the GRB prompt emission
Rodolfo Barniol Duran, Mingbin Leng, Dimitrios Giannios
In order to explain rapid light curve variability without invoking a variable source, several authors have proposed "minijets" that move relativistically relative to the main flow…
Radio rebrightening of the GRB afterglow by the accompanying supernova
Rodolfo Barniol Duran, Dimitrios Giannios
The gamma-ray burst (GRB) jet powers the afterglow emission by shocking the surrounding medium, and radio afterglow can now be routinely observed to almost a year after the explosi…
Energies of GRB blast waves and prompt efficiencies as implied by modeling of X-ray and GeV afterglows
Paz Beniamini, Lara Nava, Rodolfo Barniol Duran +1
We consider a sample of ten GRBs with long lasting () emission detected by Fermi/LAT and for which X-ray data around day are also available. We assume tha…
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…
