Quasi-periodic behaviour in the optical and γ-ray light curves of blazars 3C 66A and B2 1633+38
J. Otero-Santos, J. A. Acosta-Pulido, J. Becerra González +18
We report on quasi-periodic variability found in two blazars included in the Steward Observatory Blazar Monitoring data sample: the BL Lac object 3C 66A and the Flat Spectrum Radio…
Dissecting the long-term emission behaviour of the BL Lac object Mrk 421
M. I. Carnerero, C. M. Raiteri, M. Villata +4
We report on long-term multi-wavelength monitoring of blazar Mrk 421 by the GASP-WEBT collaboration and Steward Observatory, and by the Swift and Fermi satellites. We study the sou…
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…
Gamma-ray emission region located in the parsec scale jet of OJ287
Ivan Agudo, Svetlana G. Jorstad, Alan P. Marscher +8
We report on the location of the gamma-ray emission region in flares of the BL Lacertae object OJ287 at >14pc from the central supermassive black hole. We employ data from multi-sp…
