Abstract

AbstractExtragalactic jets launched from the immediate vicinity of supermassive black holes in radio‐loud active galactic nuclei (AGN) are key objects in modern astronomy and astroparticle physics. AGN jets carry a fraction of the total gravitational energy released during the accretion of matter onto supermassive black holes and are prime suspects as possible sources of ultrahigh‐energy cosmic rays and the recently detected extraterrestrial neutrinos at PeV energies. TANAMI (Tracking Active galactic Nuclei with Austral Milliarcsecond Interferometry) is a multiwavelength program monitoring AGN jets of the southern sky. It combines high‐resolution imaging and spectral monitoring at radio wavelengths with higher‐frequency observations at IR, optical/UV, X‐ray, and γ‐ray energies. We review recent results of the TANAMI program, highlighting AGN candidate neutrino‐emitters in the error circles of the IceCube PeV neutrino events. (© 2015 WILEY‐VCH Verlag GmbH & Co.
