Description
Summary:GRB 170817A is the electromagnetic counterpart of the gravitational wave signal GW 170817. Observations of this event are best explained by a structured jet model in which energy per solid angle is a function of the distance from the jet axis. In our work, we investigate a two-component model of the jet, where the narrow component is more energetic and has a higher Lorentz factor, while a wide component is less energetic, and shows a lower Lorentz factor. By means of the numerical software BOXFIT, we produce the light-curves of radio (3GHz) and optical band (R band). We also show that we can distinguish the two different models with observations provided by VLA, SKA, 1m, 4m and 8m telescopes.
