Jet Kinematic Analysis of TeV Radio Galaxies using High-Resolution Radio Images — •Kevin Schmidt, Lena Linhoff, and Simone Mender — TU Dortmund, Experimentelle Physik Vb

In the last years, a new class of TeV emitters has been discovered, the so-called TeV radio galaxies. These are observed under larger viewing angles than blazars, which allows a direct view of their jet’s morphologies. As they show features of both blazars and radio galaxies, the observed properties provide strong challenges for existing emission models. Expanding the group of TeV radio galaxies is essential to define their characteristics and learn about the acceleration mechanisms of active galactic nuclei (AGN) in general.

A central feature for the classification of AGN is their viewing angle relative to our line of sight. One opportunity to estimate the viewing angle is to study the jet characteristics using high-resolution radio images obtained by VLBI measurements. In this talk, a framework for jet kinematic analysis is presented using the example of 3C 264, the most recently discovered TeV radio galaxy.
