Radio-optical scrutiny of the central engine in compact AGN
T. G. Arshakian, V. H. Chavushyan, E. Ros +2
We combine Very-Long-Baseline Interferometry (VLBI) data for active galactic nuclei (AGN) available from the Very Large Baseline Array (VLBA) 2 cm imaging survey and opti…
Sub-milliarcsecond Imaging of Quasars and Active Galactic Nuclei III. Kinematics of Parsec-Scale Radio Jets
K. I. Kellermann, M. L. Lister, D. C. Homan +6
We report the results of a 15 GHz (2 cm) multi-epoch VLBA program, begun in 1994 to study the outflow in radio jets ejected from quasars and active galaxies. The observed flow of 2…
A Multi-Frequency Study of 3C309.1
E. Ros, A. P. Lobanov
Here we summarize our results from a detailed multi-frequency study of the QSO 3C309.1 based on the Very Long Baseline Array (VLBA) observations made in mid 1998. From our images,…
NGC1052 - A study of the pc-scale twin jet
M. Kadler, E. Ros, J. A. Zensus +2
We present results of a VLBA multi-frequency study of the pc-scale twin jet in NGC1052. We observed this object at epoch 1998.99 with the VLBA at 5, 8.4, 22 and 43 GHz both in tota…
The quasar 3C345 at the highest resolution with mm- and space-VLBI
J. Klare, J. A. Zensus, T. P. Krichbaum +2
The quasar 3C345 is one of the best examples of extragalactic jet with superluminal components moving on helical paths. To get better constraints on the jet physics, we have imaged…
