The discovery of GRB 170817A, the first unambiguous off-axis short gamma-ray burst arising from a neutron star merger, has challenged our understanding of the angular structure of relativistic jets. The late afterglow of GRB 170817A has been described by a structured jet seen slightly off-axis (at an observer angle of $\approx 20^\circ$--$30^\circ$). Studies of the jet dynamics and propagation usually assume that the jet is ejected from the central engine with a top-hat structure and its final… CONTINUE READING
