Abstract
The Southern Hemisphere VLBI monitoring program TANAMI provides dual-frequency (8 GHz and 22 GHz), milliarcsecond monitoring of extragalactic jets south of −30◦ declination. The TANAMI sample consists of a combined radio and γ-ray selected subsample of currently ∼ 80 AGN jets, with new γ-ray bright sources being added upon detections by Fermi/LAT. Supporting
programs provide simultaneous multiwavelength coverage of all sources, in order to construct broadband spectral energy distributions (SEDs) of flaring and quiescence source states, as well as a rapid follow-up of high-energy flares. This combined setup allows us to continuously study the spectral and structural evolution of highly energetic extragalactic jets and test correlations in different wavebands, providing crucial information on underlying physical mechanisms. Here, we present jet kinematics of Centaurus A and show preliminary VLBI results on PKS 0625–354 and the time-dependent spectral index image of PKS 0537–441.
