Detection Confidence Tests for Burst and Inspiral Candidate Events
R. Gouaty (for the LIGO Scientific Collaboration)

TL;DR
This paper discusses a methodology for validating gravitational-wave candidate events by applying various tests to distinguish true signals from false alarms caused by detector noise.
Contribution
It introduces a general validation methodology for gravitational-wave candidates, incorporating multiple tests to improve confidence in detections.
Findings
Validation tests effectively differentiate true signals from false alarms.
The methodology is demonstrated with simulated gravitational-wave signals.
The approach enhances the reliability of gravitational-wave detection pipelines.
Abstract
The LIGO Scientific Collaboration (LSC) is developing and running analysis pipelines to search for gravitational-wave transients emitted by astrophysical events such as compact binary mergers or core-collapse supernovae. However, because of the non-Gaussian, non-stationary nature of the noise exhibited by the LIGO detectors, residual false alarms might be found at the end of the pipelines. A critical aspect of the search is then to assess our confidence for gravitational waves and to distinguish them from those false alarms. Both the 'Compact Binary Coalescence' and the 'Burst' working groups have been developing a detection checklist for the validation of candidate-events, consisting of a series of tests which aim to corroborate a detection or to eliminate a false alarm. These tests include for example data quality checks, analysis of the candidate appearance, parameter consistency…
