Monitoring of AGN Jets with Very-High-Energy Astroparticle Emission

The TELAMON program is using the Effelsberg 100-m telescope to monitor the radio spectra of active galactic nuclei (AGN) under scrutiny in astroparticle physics, namely TeV blazars and candidate neutrino-associated AGN. The large Effelsberg dish can yield superior radio data over other programs for very-high-energy (VHE) emitting blazars, which are often faint radio sources. We perform high-frequency observations every 2-4 weeks at multiple frequencies up to 44 GHz. We aim to characterize the radio variability of very-high energy emitting AGN jets and trace dynamical processes in the pc-scale jets of blazars related to high-energy flares or neutrino detections. Student thesis topics are offered in the context of improved calibration and data-handling schemes as well as studies of the variability properties of TELAMON sources, e.g., in the context of contemporary multiwavelength and neutrino observations.
