Short GRBs: opening angles, local neutron star merger rate and off-axis events for GRB/GW association

Zhi-Ping Jin, Xiang Li, Hao Wang +7

The jet breaks in the afterglow lightcurves of short gamma-ray bursts (SGRBs), rarely detected so far, are crucial for estimating the half-opening angles of the ejecta (${\theta }_{\mathrm{j}}$…
