The origin of high-energy astrophysical neutrinos remains unresolved, and secure electromagnetic counterparts to individual events are rare despite rapid follow-up. Dusty star-forming galaxies at cosmic noon (redshift of z ≈ 1-4) are natural cosmic-ray calorimeters, yet observational links between these galaxies and neutrinos have remained unknown. Urata et al. report a compact-core, dusty star-forming galaxy within an IceCube localization, JCMT0402-0424, a quadruply lensed galaxy at z = 2.988 located inside the 90% containment region of the IceCube event IC 210922A.
