| Abstract: |
We report results of multi-frequency VLBI polarization observations of the gamma-ray blazar Mkn 421, coordinated with monitoring of its TeV emission with the CAT ground-based Cerenkov telescope. These observations revealed very obvious changes in the core region of Mkn 421 on time scales of a few weeks, at a time when it showed strong TeV activity. The paper will discuss possible correlations between radio core properties and high-energy events in the context of a VLBI-TeV connection. |
