Leveraging cross-detector parameter consistency measures to enhance sensitivities of gravitational wave searches
Sayantan Ghosh, Leigh Smith, Jiyoon Sun +3
All-sky searches for generic short-duration astrophysical GW transients are often challenging because of noise transients. Developing novel signal-noise discriminators is crucial f…
