Abstract: LIGO detectors based on laser interferometry have been constructed aiming for detection of gravitational waves. Having broadband sensitivity, they are well suited for detection of the GW bursts - transients of gravitational radiation with a relatively short duration, typically less then a second. The GW bursts are expected to be produced by astrophysical sources such as supernova collapse and other energetic cosmic phenomena. Due to poor theoretical understanding of sources, various robust data analysis techniques are used for LIGO burst searches. One of the very promising techniques is based on wavelet transformations which provide a natural basis for burst signals because of good localization of wavelet waveforms both in time and frequency. The speaker will talk about the LIGO detectors, anticipated burst sources, applications of wavelets for burst searches and recent LIGO results.
