Classification methods for noise transients in advanced gravitational-wave detectors II: performance tests on Advanced LIGO data

Powell, Jade, Torres-Forné, Alejandro, Lynch, Ryan et al.

Understand

The data taken by the advanced LIGO and Virgo gravitational-wave detectors contains short duration noise transients that limit the significance of astrophysical detections and reduce the duty cycle of the instruments.

  • As the advanced detectors are reaching sensitivity levels that allow for multiple detections of astrophysical gravitational-wave sources it is crucial to achieve a fast and accurate characterization of non-astrophysical transient noise shortly after it occurs in the detectors.
  • Previously we presented three methods for the classification of transient noise sources.
  • They are Principal Component Analysis for Transients (PCAT), Principal Component LALInference Burst (PC-LIB) and Wavelet Detection Filter with Machine Learning (WDF-ML).
