Photospheric emission from long duration gamma-ray bursts powered by variable engines

Creator:

López-Cámara, Diego, Morsony, Brian J., and Lazzati, Davide

Abstract:

We present the results of a set of numerical simulations of long-duration gamma-ray burst jets aimed at studying the effect of a variable engine on the peak frequency of the photospheric emission. Our simulations follow the propagation of the jet inside the progenitor star, its break-out, and the subsequent expansion...
