Description
The coincident observation of GW170817 and GRB170817A has provided unprecedented insight into the physical connection between binary neutron star mergers and short gamma-ray bursts. In this work, we perform a multi-messenger study with the aim of constraining the jet geometry of sGRBs, assuming that all BNS mergers produce relativistic jets. Our analysis incorporates gravitational-wave data from GW170817 and GW190425, together with the prompt and afterglow emission of GRB170817A. We also include the short-GRB detection rate from more than ten years of Swift monitoring to place constraints on the underlying BNS merger rate and jet structure.
