Description

I review the results of searches for gravitational-wave signals associated with gamma-ray bursts carried out in the first three observing runs of Advanced LIGO and Advanced Virgo. During this stretch of time, the spectacular GW170817-GRB 170817A event was observed, and constraints on the low-luminosity short gamma-ray burst population were placed. In the coming years, an increase in sensitivity of the gravitational-wave detector network is expected to yield more joint detections. I discuss the prospects for this scenario and show how the analysis of combined gravitational-wave and electromagnetic data from the same event can improve measurements of the inclination angle of the source, by breaking the degeneracy between the viewing and the jet opening angles.
