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...
The LIGO-Virgo-KAGRA (LVK) collaboration has detected over 300 gravitational-wave events, mostly from binary black hole (BBH) mergers. These detections enable precise inference of BBH population properties such as masses, redshift, and spins. However, the conventional spin prior—uniform in spin magnitude and isotropic in orientation—assigns near-zero probability density near effective spin...
