  • The binary neutron star (BNS) merger event GW170817 clearly shows that a BNS merger launches a short Gamma-Ray Burst (sGRB) jet. Unlike collapsars, where the ambient medium is static, in BNS mergers the jet propagates through the merger ejecta that is expanding outward at substantial velocities (∼ 0.2c). Here, we present semi-analytic and analytic models to solve the propagation of GRB jets through their surrounding media. We also perform a series of 2D numerical simulations of jet propagation… CONTINUE READING
