Abstract

Radio galaxies are relatively faint at γ-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 γ-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 highresolution 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 γ-ray AGN PKS 0521−36.

AB  - Radio galaxies are relatively faint at γ-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 γ-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 highresolution 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 γ-ray AGN PKS 0521−36.
