Abstract: We present the results of a search for gravitational-wave bursts associatedwith 137 gamma-ray bursts GRBs that were detected by satellite-basedgamma-ray experiments during the fifth LIGO science run and first Virgo sciencerun. The data used in this analysis were collected from 2005 November 4 to 2007October 1, and most of the GRB triggers were from the Swift satellite. Thesearch uses a coherent network analysis method that takes into account thedifferent locations and orientations of the interferometers at the threeLIGO-Virgo sites. We find no evidence for gravitational-wave burst signalsassociated with this sample of GRBs. Using simulated short-duration <1 swaveforms, we set upper limits on the amplitude of gravitational wavesassociated with each GRB. We also place lower bounds on the distance to eachGRB under the assumption of a fixed energy emission in gravitational waves,with typical limits of D ~ 15 Mpc E GW^iso - 0.01 M o c^2^1-2 for emission atfrequencies around 150 Hz, where the LIGO-Virgo detector network has bestsensitivity. We present astrophysical interpretations and implications of theseresults, and prospects for corresponding searches during future LIGO-Virgoruns.
