Probing the polarization characteristics of SS433 on mas scales
Z. Paragi, R. C. Vermeulen, D. C. Homan +5
We present a status report of dedicated circular polarization (CP) global VLBI observations of SS433. The total intensity image of the source is presented. We do not detect linear…
The unfriendly ISM in the radio galaxy 4C12.50 (PKS 1345+12)
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +4
The radio source 4C12.50 has often been suggested to be a prime candidate for the link between ultraluminous infrared galaxies and young radio galaxies. A VLBI study of the neutral…
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…
Relativistic Phenomena in Active Galactic Nuclei
M. H. Cohen, M. L. Lister, R. C. Vermeulen
The idea that the radio jets in AGN contain material in relativistic motion is supported by many lines of observational evidence, including morphology, brightness temperature estim…
