Title: Probing the nature of relativistic outflows in binary mergers

Abstract: Latest observations of GW170817/GRB 170817A show increasing evidence for the presence of a relativistic jet. In this scenario, the prompt and afterglow emission of GRB 170817A very likely originates from a structured jet viewed off-axis. In this talk, I will discuss our latest work investigating these non-thermal counterparts of binary mergers using simulations of a post-merger system, starting at the central engine. We follow the jet as it is self-consistently launched from the scale of the compact object of the post-merger system, out to large distances. The resulting jet naturally develops a structure whose emission can explain the properties of both the prompt and afterglow emission of GRB 170817A.​
