Waveform reconstruction with coherent WaveBurst algorithm

ORAL

Abstract

The coherent WaveBurst (cWB) algorithm uses a coherent method for detection and reconstruction of transient gravitational wave signals (bursts) by using the constrained likelihood method. The likelihood statistic is built up as a coherent sum over detector responses in the time frequency domain and represents the total signal-to-noise ratio of the GW signal detected in the network. The reconstruction of a GW event by the pipeline includes both the sky location and the signal waveforms. Once the first GW signal is detected, the astrophysical interpretation and the characterization of the emission will depend on the reliability of the waveform reconstruction process. The performances of the pipeline on the reconstruction of the signal parameters is reported.
