A new method to distinguish gravitational-wave signals from detector noise transients with Gravity Spy
arXiv (Cornell University)(2023)
摘要
The Advanced LIGO and Advanced Virgo detectors have enabled the confident
detection of dozens of mergers of black holes and neutron stars. However, the
presence of detector noise transients (glitches) hinders the search for these
gravitational wave (GW) signals. We prototyped a restructuring of Gravity Spy's
classification model to distinguish between glitches and astrophysical signals.
Our method is able to correctly classify three-quarters of retracted candidate
events in O3b as non-astrophysical and 100% of the confirmed astrophysical
events as true signals. This approach will inform candidate event validation
efforts in the latest observing run.
