Total intensity and polarized emission of the parsec-scale jet in 3C345
E. Ros, J. A. Zensus, A. P. Lobanov
We have studied the parsec-scale structure of the quasar 3C345 at λλ1.3, 2, 3.6, and 6 cm, using total intensity and linear polarization images from 3 epochs of VLBA observations m…
High Angular Resolution Monitoring of Prominent AGN at 86 GHz
T. P. Krichbaum, A. Witzel, J. A. Zensus
We report results from 3mm-VLBI observations of 3C273 and 3C454.3 during the period 1994-1997. In both sources the images show superluminal motion in feature-rich jets. Due to the…
SKA in VLBI: Impact on Studies of Small Scale Structures in Active Galactic Nuclei
T. P. Krichbaum, A. Witzel, J. A. Zensus
We discuss the advantages which the next generation interferometer SKA (the Square Kilometer Array) will bring for Very Long Baseline Interferometry (VLBI) at centimeter wavelength…
Unusual radio variability in the BL Lac object 0235+164
A. Kraus, A. Quirrenbach, A. P. Lobanov +11
We present radio observations at three frequencies and contemporaneous optical monitoring of the peculiar BL Lac object AO 0235+164. During a three-week campaign with the VLA we ob…
Radiospectra and kinematics in blazars
A. P. Lobanov, A. Kraus, J. A. Zensus
Broad band spectra of total and compact--scale radio emission from blazars, used in combination with kinematic information inferred from VLBI monitoring programs, can be applied su…
