Abstract
Supernovae are an anticipated source of gravitational radiation within the sensitive frequency range of the interferometers of the Laser Interferometer Gravitational-Wave Observatory (LIGO) project. A search for gravitational wave bursts from core collapse supernovae has been performed on the data of the gravitational wave channels of the 2 km and 4 km LIGO Hanford interferometers for the third science run. The method used an optimal filter based on 201 waveform templates. These included 78 Zwerger-Muller, 52 Dimmelmeier-Font-Muller and 71 Ott-Burrows-Livne-Walder simulated core collapse supernova waveforms. The efficiency of coincident detection of signals in both interferometers, and the rate of false alarms, have been estimated. Hardware and software injection of simulated waveforms into the interferometer data were used in the analysis. Estimates are made of the sensitivity for future LIGO runs, involving all three of the LIGO interferometers.
