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…
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…
Polarization of AGN Jets
Daniel C. Homan
The sensitivity, stability, and uniformity of calibration of the VLBA has revolutionized parsec-scale polarization studies of AGN jets. Not only does polarization probe the magneti…
Multi-Frequency VSOP and VLBA Polarization Observations of 3C279 and 3C345
C. C. Cheung, D. H. Roberts, J. F. C. Wardle +2
This contribution presents preliminary results from coordinated polarization sensitive VSOP and VLBA imaging of the blazars 3C~279 and 3C~345 at multiple frequencies.
Variability and Velocity of Superluminal Sources
M. H. Cohen, M. A. Russo, D. C. Homan +5
We investigate the relation between the Doppler factor determined from variations in total flux at 22 and 37 GHz, and the apparent transverse velocity determined from VLBA observat…
Superluminal Motion and Relativistic Beaming in Blazar Jets
K. I. Kellermann, M. L. Lister, D. C. Homan +5
High resolution radio observations remain the most direct way to study the formation and evolution of radio jets associated with the accretion onto massive black holes. We report p…
