About the Detection of Gravitational Wave Bursts
Supernovae have been historically the first envisaged sources of gravitational waves (GW). Although binary inspirals or even periodic GW emitters like pulsars seem to be nowadays more promising sources, impulsive sources of GW such as supernovae should also be considered in the data analysis design of interferometric detectors currently under construction (LIGO, VIRGO). Impulsive GW sources are...
متن کاملMultiresolution techniques for the detection of gravitational-wave bursts
We present two search algorithms that implement logarithmic tiling of the time–frequency plane in order to efficiently detect astrophysically unmodelled bursts of gravitational radiation. The first is a straightforward application of the dyadic wavelet transform. The second is a modification of the windowed Fourier transform which tiles the time–frequency plane for a specific Q. In addition, we...
متن کاملCoherent method for detection of gravitational wave bursts
We describe a coherent network algorithm for detection and reconstruction of gravitational wave bursts. The algorithm works for two and more arbitrarily aligned detectors and can be used for both all-sky and triggered burst searches. We describe the main components of the algorithm, including the time-frequency analysis in wavelet domain, construction of the likelihood time-frequency maps, the ...

متن کاملTriggers for the Detection of Gravitational Wave Bursts
We present several filtering methods which can be used as triggers for the detection of gravi-tational wave bursts in interferometric detectors. All the methods are compared to matched filtering with the help of a figure of merit based on the detection of supernovae signals simulated by Zwerger and Müller.
