Synchrotron Outbursts in Galactic and Extra-galactic Jets, Any Difference?
M. Turler, E. J. Lindfors
We discuss differences and similarities between jets powered by super-massive black holes in quasars and by stellar-mass black holes in microquasars. The comparison is based on mul…
Frequency-dependent time delays for strong outbursts in four blazars from the Metsahovi and UMRAO monitoring databases
T. B. Pyatunina, N. A. Kudryavtseva, D. C. Gabuzda +4
The combined data of the University of Michigan Radio Astronomy Observatory and Metsahovi Radio Observatory provide us with radio light curves for Active Galactic Nuclei monitored…
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…
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…
An Extremely Curved Relativistic Jet in PKS 2136+141
Tuomas Savolainen, Kaj Wiik, Esko Valtaoja +5
We report the discovery of an extremely curved jet in the radio-loud quasar PKS2136+141. Multi-frequency Very Long Baseline Array (VLBA) images show a bending jet making a turn-aro…
