Association of IceCube neutrinos with radio sources observed at Owens Valley and Mets\"ahovi Radio Observatories

Understand

Identifying the most likely sources for high-energy neutrino emission has been one of the main topics in high-energy astrophysics ever since the first observation of high-energy neutrinos by the IceCube Neutrino Observatory.

• Active galactic nuclei with relativistic jets, also known as blazars, have been considered to be one of the main candidates because of their ability to accelerate particles to high energies.
• We study the connection between radio emission and IceCube neutrino events using data from the Owens Valley Radio Observatory (OVRO) and Mets\"ahovi Radio Observatory blazar monitoring programs.
• We identify sources in our radio monitoring sample that are positionally consistent with IceCube high-energy neutrino events.
