TL;DR
This paper reports on searches for high-energy neutrino counterparts to gravitational-wave events detected by LIGO/Virgo, using IceCube data, but finds no significant associations and sets upper limits on neutrino emissions.
Contribution
It presents the first systematic search for neutrino counterparts to LIGO/Virgo gravitational-wave events using IceCube data, establishing upper limits on neutrino emissions.
Findings
No significant neutrino counterparts were detected.
Upper limits on neutrino emission were established for each GW event.
Constraints on the energy emitted in neutrinos from these events were derived.
Abstract
We summarize initial results for high-energy neutrino counterpart searches coinciding with gravitational-wave events in LIGO/Virgo's GWTC-2 catalog using IceCube's neutrino triggers. We did not find any statistically significant high-energy neutrino counterpart and derived upper limits on the time-integrated neutrino emission on Earth as well as the isotropic equivalent energy emitted in high-energy neutrinos for each event.
