Impact of noise transients on gravitational-wave burst detection efficiency of the BayesWave pipeline with multi-detector networks

Understand

Detection confidence of the source-agnostic gravitational-wave burst search pipeline BayesWave is quantified by the log signal-versus-glitch Bayes factor, $\ln\mathcal{B}_{\mathcal{S},\mathcal{G}}$.

• A recent study shows that $\ln\mathcal{B}_{\mathcal{S},\mathcal{G}}$ increases with the number of detectors.
• However, the increasing frequency of non-Gaussian noise transients (glitches) in expanded detector networks is not accounted for in the study.
• Glitches can mimic or mask burst signals resulting in false alarm detections, consequently reducing detection confidence.
