Effects of the turbulent ISM on radio observations of quasars
K. É. Gabányi, S. Britzen, T. P. Krichbaum +5
In radio bands, the study of compact radio sources can be affected by propagation effects through the Interstellar Medium. These are usually attributed to the presence of turbulent…
Rapid and correlated variability of blazar S5 0716+71 from radio- to sub-mm bands
L. Fuhrmann, T. P. Krichbaum, A. Witzel +9
The BL Lac object S5 0716+71 was target of a coordinated and global multi-frequency campaign to search for rapid and correlated variability and signatures of the inverse-Compton ca…
VLBI at the highest frequencies - AGN studied with micro-arcsecond resolution
T. P. Krichbaum, I. Agudo, U. Bach +2
Compact galactic and extragalactic radio sources can be imaged with an unsurpassed angular resolution of a few ten micro-arcseconds, adopting the observing technique of global mill…
"Oscillating" components in the BL Lac object 0716+714?
S. Britzen, V. Meyer, A. Witzel +5
15 VLBA observations of the BL Lac object 0716+714, performed between 1994.67 and 2006.40 at 15 GHz, have been analyzed. Part of the data (12 epochs) were obtained within the Mojav…
The Kinematics of S5 1803+784
N. A. Kudryavtseva, S. Britzen, A. Witzel +8
We present the results of a multi-frequency analysis of the structural variability in the parsec-scale jet of the blazar S5 1803+784. More than 90 epochs of observations at 6 frequ…
A global 86 GHz VLBI survey
S. Lee, A. P. Lobanov, T. P. Krichbaum +5
We present results from a large global VLBI(Very Long Baseline Interferometry) survey of compact radio sources at 86 GHz which started in October 2001. The main goal of the survey…
