Gravitational-wave bursts with GRBs

The data used in this analysis were collected from 2005 November 4 to 2007 October 1, and most of the GRB triggers were from the Swift satellite. The search uses a coherent network analysis method that takes into account the different locations and orientations of the interferometers at the three LIGO-Virgo sites.

We find no evidence for GWB signals associated with this sample of GRBs. Using simulated short-duration (<1s) waveforms, we set upper limits on the amplitude of gravitational waves associated with each GRB. We also place lower bounds on the distance to each GRB under the assumption of a fixed energy emission in gravitational waves, with a median limit of D~12Mpc(E^iso^_GW_/0.01M_{sun}_c^2^)^1/2^ for emission at frequencies around 150Hz, where the LIGO-Virgo detector network has best sensitivity.
