Description
The detection of TeV-PeV neutrinos by the IceCube Neutrino Observatory, alongside KM3Net and Baikal-GVD, has unveiled a new view into the most extreme high-energy processes in the universe. As of 2024, nearly 300 astrophysical track-like TeV-PeV neutrino events have been detected, though their exact astrophysical counterparts remain largely unidentified, limited by the localization accuracy of current neutrino observatories. However, growing evidence suggests a strong association between these high-energy neutrinos and supermassive black holes with powerful relativistic jets. In this talk, I will review some leading astrophysical scenarios for high-energy neutrino production, highlighting recent multi-messenger approaches that combine neutrino detections with electromagnetic observations from radio to gamma-ray wavelengths. I will also present our ongoing studies using high-resolution very-long-baseline interferometric observations of IceCube neutrino fields to study candidate sources. Additionally, I will briefly introduce the Square Kilometer Array (SKA), an upcoming transformative radio telescope array that will enable high-resolution, real-time monitoring of the dynamic high-energy universe.
