"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…
Multifrequency variability of the blazar AO 0235+164. The WEBT campaign in 2004-2005 and long-term SED analysis
C. M. Raiteri, M. Villata, M. Kadler +3
A huge multiwavelength campaign targeting the blazar AO 0235+164 was organized by the Whole Earth Blazar Telescope (WEBT) in 2003-2005 to study the variability properties of the so…
Synchrotron flaring in the jet of 3C 279
E. J. Lindfors, M. Türler, E. Valtaoja +8
We study the synchrotron flaring behaviour of the blazar 3C279 based on an extensive dataset covering 10 years of monitoring at 19 different frequencies in the radio-to-optical ran…
A Quasi-Periodic Modulation of the Radio Light Curve of the Blazar PKS B0048-097
M. Kadler, P. A. Hughes, E. Ros +2
In this letter we present the results of a wavelet analysis of the radio light curve of the BL Lac Object PKS B0048-097 from the University of Michigan Radio Astronomy Observatory…
Structure and flux variability in the VLBI jet of BL Lacertae during the WEBT campaigns (1995--2004)
U. Bach, M. Villata, C. M. Raiteri +9
BL Lacertae has been the target of several observing campaigns by the Whole Earth Blazar Telescope (WEBT) collaboration and is one of the best studied blazars at all accessible wav…
