X-ray afterglow limits on the viewing angles of short gamma-ray bursts
The behaviour of a short gamma-ray burst (sGRB) afterglow light curve can reveal the
angular structure of the relativistic jet and constrain the observer's viewing angle. The …

Possible origin of AT2021any: A failed gamma-ray burst from a structured jet
F Xu, YF Huang, JJ Geng - Astronomy & Astrophysics, 2023 - aanda.org
Afterglows not associated with any gamma-ray bursts (GRBs) are called orphan afterglows.
The detection of such afterglows is an important goal in many sky survey programs …
