ALMA Identifies Ancient Starburst Galaxy as Likely Source of IceCube High-Energy Neutrino
Summary
Astronomers using ALMA have identified a compact, intensely star-forming galaxy from 11 billion years ago as the most likely source of a high-energy neutrino detected by IceCube. Gravitational lensing allowed detailed study of this dust-obscured galaxy, which is the strongest electromagnetic counterpart candidate linked to an IceCube neutrino event. The discovery helps bridge multi-messenger astronomy, connecting neutrino detections with their cosmic origins.
