Astronomers Trace Elusive High-Energy Neutrino to Star-Forming Galaxy in Early Universe

17 June 2026 at 20:48

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.

JCMT0402-0424, a dusty starburst galaxy around 11 billion light-years away, is the strongest candidate yet for the source of the high-energy neutrino event IC 210922A, according to a team of astronomer led by Yuji Urata of MITOS Science Co.

Using NASA’s Goldstone Solar System Radar and NSF’s Green Bank Telescope, astronomers from the University of California, Los Angeles, confirmed that the icy surface of Jupiter’s moon Europa scatters radio energy in an unusually strong and complex way not seen on rocky worlds.
