Multiple Rebrightenings in the Optical Afterglow of GRB 210731A: Evidence for an Asymmetric Jet

The broadband afterglow of gamma-ray bursts (GRBs) is usually believed to originate from the synchrotron radiation of electrons accelerated by the external shock of relativistic jets. Therefore, the jet structure should have a significant impact on the GRB afterglow features. The latest observations...
