Search for TeV Radio Galaxies Using High-Resolution Radio Images — •Kevin Schmidt, Lena Linhoff, and Simone Mender — TU Dortmund, Lehrstuhl für Experimentelle Physik Vb, Otto-Hahn-Straße 4a, 44227 Dortmund

Active galactic nuclei (AGN) belong to the most powerful sources in the universe. They dominate the gamma-ray sky and are regularly observed by imaging cherenkov telescopes. In the past years a new class of very-high-energy emitters was found, the TeV radio galaxies. These sources show big differences to existing models, therefore they are interesting objects for studies.

With the help of morphological radio analysis promising sources can be extracted from a sample of candidates. This can be achieved by obtaining important characteristics from high-resolution images made by radio interferometers. Finding more TeV radio galaxies is necessary to learn about the properties of this type of AGN and its emission processes. In this talk first results of the ongoing analysis of high-resolution radio images of some TeV radio galaxy candidates will be presented.
