  Extragalactic 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 $\gamma$-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.
