A coherent consistency test for gravitational-wave bursts

A common feature of gravitational-wave bursts is that their waveforms are unknown or poorly modelled. This lack of knowledge could make it difficult to distinguish between real signals and coincidental noise fluctuations in gravitational-wave detectors. We present a multi-detector coherent analysis test that can distinguish unmodelled gravitational-wave bursts from interferometer 'glitches', without requiring any a priori knowledge of the gravitational-wave signal. We demonstrate this algorithm using a population of simulated core-collapse supernova waveforms and simulated noise glitches.
