Kinematic Study of the Blazar 0716+714
U. Bach, T. P. Krichbaum, S. Britzen +3
We determined the kinematics at the jet of 0716+714 from a reanalysis of multi-frequency VLBI data (5, 8.4, 15, 22 GHz) obtained during the last 10 years combined with data from th…

Multi-frequency & Multi-epoch VLBI study of Cygnus A
U. Bach, M. Kadler, T. P. Krichbaum +4
We present the first multi-frequency phase-referenced observations of Cygnus A done with the VLBA at 15 and 22 GHz. We find a pronounced two-sided jet structure, with a steep spect…

Where has all the polarization gone?
E. Middelberg, A. L. Roy, U. Bach +2
We have observed the five radio galaxies NGC1052, NGC4261, Hydra A, Centaurus A and Cygnus A with polarimetric VLBI at 15 GHz to look for possible Faraday rotation in foreground ab…
