Anatomy of helical relativistic jets: The case of S5 0836+710
Manel Perucho, Yuri Y. Kovalev, Andrei P. Lobanov +2
Helical structures are common in extragalactic jets. They are usually attributed in the literature to periodical phenomena in the source (e.g., precession). In this work, we use VL…
The long-lasting activity of 3C 454.3. GASP-WEBT and satellite observations in 2008-2010
C. M. Raiteri, M. Villata, M. F. Aller +6
We present multiwavelength observations of 3C 454.3 from April 2008 to March 2010. The radio to optical data are mostly from the GASP-WEBT, UV and X-ray data from Swift, and gamma-…
Another look at the BL Lacertae flux and spectral variability
C. M. Raiteri, M. Villata, L. Bruschini +52
The GLAST-AGILE Support Program (GASP) of the Whole Earth Blazar Telescope (WEBT) monitored BL Lacertae in 2008-2009 at radio, near-IR, and optical frequencies. During this period,…
Non-radial motion in the TeV blazar S5 0716+714 The pc-scale kinematics of a BL Lac Object
S. Britzen, V. A. Kam, A. Witzel +6
For the BL Lac object S5 0716+714 conflicting apparent velocities of jet component motion have been reported in the literature. This object is an intra-day variable source and suit…
The GASP-WEBT monitoring of 3C 454.3 during the 2008 optical-to-radio and gamma-ray outburst
M. Villata, C. M. Raiteri, M. A. Gurwell +6
Since 2001, the radio quasar 3C 454.3 has undergone a period of high optical activity, culminating in the brightest optical state ever observed, during the 2004-2005 outburst. The…
