Investigation of the correlation patterns and the Compton dominance variability of Mrk 421 in 2017
MAGIC Collaboration, V. A. Acciari, S. Ansoldi +284
We present a detailed characterisation and theoretical interpretation of the broadband emission of the paradigmatic TeV blazar Mrk 421, with special focus on the multi-band flux co…
The complex variability of blazars: Time-scales and periodicity analysis in S4 0954+65
C. M. Raiteri, M. Villata, V. M. Larionov +3
Among active galactic nuclei, blazars show extreme variability properties. We here investigate the case of the BL Lac object S4 0954+65 with data acquired in 2019-2020 by the Trans…
Two Flares with One Shock: the Interesting Case of 3C 454.3
I. Liodakis, D. Blinov, S. G. Jorstad +18
The quasar 3C 454.3 is a blazar known for its rapid and violent outbursts seen across the electromagnetic spectrum. Using gamma-ray, X-ray, multi-band optical, and very long baseli…
Polarization angle swings in blazars: The case of 3C 279
S. Kiehlmann, T. Savolainen, S. G. Jorstad +61
Over the past few years, several occasions of large, continuous rotations of the electric vector position angle (EVPA) of linearly polarized optical emission from blazars have been…
A multi-wavelength polarimetric study of the blazar CTA 102 during a Gamma-ray flare in 2012
Carolina Casadio, José L. Gómez, Svetlana G. Jorstad +28
We perform a multi-wavelength polarimetric study of the quasar CTA 102 during an extraordinarily bright -ray outburst detected by the {\it Fermi} Large Area Telescope in Septemb…
The Outburst of the Blazar S40954+658 in March-April 2011
D. A. Morozova, V. M. Larionov, I. S. Troitsky +22
We present the results of optical (R band) photometric and polarimetric monitoring and Very Long Baseline Array (VLBA) imaging of the blazar S4 0954+658, along with Fermi and gamma…
The awakening of BL Lacertae: observations by Fermi, Swift, and the GASP-WEBT
C. M. Raiteri, M. Villata, F. D'Ammando +4
Since the launch of the Fermi satellite, BL Lacertae has been moderately active at gamma-rays and optical frequencies until May 2011, when the source started a series of strong fla…
The structure and emission model of the relativistic jet in the quasar 3C 279 inferred from radio to high-energy gamma-ray observations in 2008-2010
M. Hayashida, G. M. Madejski, K. Nalewajko +90
We present time-resolved broad-band observations of the quasar 3C 279 obtained from multi-wavelength campaigns conducted during the first two years of the Fermi Gamma-ray Space Tel…
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-…
The Inner Jet of the Quasar PKS 1510089 as Revealed by Multi-waveband Monitoring
Alan P. Marscher, Svetlana G. Jorstad, Francesca D. D'Arcangelo +22
As part of our comprehensive long-term multi-waveband monitoring of 34 blazars, we followed the activity in the jet of the blazar PKS 1510-089 during major outbursts during the fir…
