Abstract: Jet precession is thought to be a ubiquitous phenomenon in astronomical events of various scales, including gamma-ray bursts (GRBs). If GRB jets undergo precession, periodic features might be introduced into their light curves. Detecting these periodic signals is therefore crucial for confirming the properties of GRBs’ central engines. However, periodic signals are always missing from observed GRB light curves. Against this backdrop, the broader effects of jet precession on GRBs have been widely studied. In this review, we summarize recent research progress on jet precession in GRBs. The main content focuses on four aspects of the effects of jet precession on GRBs: light curves, jet structures, polarization, and gravitational waves.
