Location of gamma-ray Flare Emission in the Jet of the BL Lacertae Object OJ287 more than 14pc from the Central Engine
Ivan Agudo, Svetlana G. Jorstad, Alan P. Marscher +18
We combine time-dependent multi-waveband flux and linear polarization observations with sub-milliarcsecond-scale polarimetric images at lambda=7mm of the BL Lacertae-type blazar OJ…
Flaring Behavior of the Quasar 3C~454.3 across the Electromagnetic Spectrum
Svetlana G. Jorstad, Alan P. Marscher, Valeri M. Larionov +29
We analyze the behavior of the parsec-scale jet of the quasar 3C~454.3 during pronounced flaring activity in 2005-2008. Three major disturbances propagated down the jet along diffe…
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…
Probing the Inner Jet of the Quasar PKS 1510-089 with Multi-waveband Monitoring during Strong Gamma-ray Activity
Alan P. Marscher, Svetlana G. Jorstad, Valeri M. Larionov +29
We present results from monitoring the multi-waveband flux, linear polarization, and parsec-scale structure of the quasar PKS 1510-089, concentrating on eight major gamma-ray flare…
Synchronous Optical and Radio Polarization Variability in the Blazar OJ287
F. D. D'Arcangelo, A. P. Marscher, S. G. Jorstad +12
We explore the variability and cross-frequency correlation of the flux density and polarization of the blazar OJ287, using imaging at 43 GHz with the Very Long Baseline Array, as w…
Rapid Multiwaveband Polarization Variability in the Quasar PKS 0420-014: Optical Emission from the Compact Radio Jet
Francesca D. Darcangelo, Alan P. Marscher, Svetlana G. Jorstad +6
An 11-day monitoring campaign in late 2005 reveals clear correlation in polarization between the optical emission and the region of the intensity peak (the "pseudocore") at the ups…
