The authors performed an unmodeled, targeted search for gravitational‑wave transients coincident with high‑energy neutrinos detected by IceCube during LIGO‑Virgo’s third observing run, finding no significant signals and placing distance limits on possible sources.
Abstract
We search for generic gravitational-wave transients associated with high-energy neutrinos detected by the IceCube Neutrino Observatory during the third Observing Run (O3) of Advanced LIGO, Advanced Virgo, and KAGRA. We perform an unmodeled, targeted search, which is sensitive to gravitational-wave signals weaker than those reported in real time or in the gravitional-wave transient catalog, and can thus uncover coincidences missed by typical neutrino follow-up searches. We find no statistically significant gravitational-wave signal and set lower bounds on the distance of possible gravitational-wave sources for different emission models.
