Findings
High-resolution VLBI maps at 8.4 and 22.3 GHz
Preliminary jet kinematic analysis of PKS 0521-36
Insights into AGN jet properties in gamma-ray faint radio galaxies
Abstract
Radio galaxies are relatively faint at -ray energies, where they make up only 1-2% of all AGN detected by Fermi-LAT. However, they offer a unique perspective to study the intrinsic properties of AGN jets. For this reason, the combination of -ray and multi-wavelength data with high-resolution VLBI monitoring is a powerful tool to tackle the basic unanswered questions about AGN jets. Here we present preliminary results from a sample study of radio galaxies in the Southern hemisphere observed by the TANAMI VLBI monitoring program. We obtain high-resolution maps at 8.4 and 22.3 GHz, and study the jet kinematics using multi-epoch data. We present a preliminary kinematic analysis for the peculiar -ray AGN PKS 052136.
