Erratic Jet Wobbling in the BL Lacertae Object OJ287 Revealed by Sixteen Years of 7mm VLBA Observations
Ivan Agudo, Alan P. Marscher, Svetlana G. Jorstad +5
We present the results from an ultra-high-resolution 7mm Very Long Baseline Array (VLBA) study of the relativistic jet in the BL Lacertae object OJ287 from 1995 to 2011 containing…
Location of the Gamma-Ray Flaring Emission in the Parse-Scale Jet of the BL Lac Object AO 0235+164
Ivan Agudo, Alan P. Marscher, Svetlana G. Jorstad +12
We locate the gamma-ray and lower frequency emission in flares of the BL Lac object AO 0235+164 at >12pc in the jet of the source from the central engine. We employ time-dependent…
MAPCAT: Monitoring AGN with Polarimetry at the Calar Alto Telescopes
Ivan Agudo, Sol N. Molina, Jose L. Gomez +3
We introduce MAPCAT, a long-term observing program for "Monitoring of AGN with Polarimetry at the Calar Alto Telescopes". Multi-spectral-range studies are critical to understand so…
Multiwavelength Spectral Studies Of Fermi-LAT Blazars
Manasvita Joshi, Alan Marscher, Svetlana Jorstad +6
We present multiwavelength spectral analyses of two Fermi-LAT blazars, OJ 287 and 3C 279, that are part of the Boston University multiwaveband polarization program. The data have b…
Parsec-Scale Behavior of Blazars during High Gamma-Ray States
S. Jorstad, A. Marscher, I. Agudo +1
We compare the γ-ray light curves of the blazars, constructed with data provided by the Fermi Large Area Telescope, with flux and polarization variations in the VLBI core and brigh…
Gamma-ray Flaring Emission in Blazar OJ287 Located in the Jet >14 pc from the Black Hole
I. Agudo, S. G. Jorstad, A. P. Marscher +8
We combine the Fermi-LAT light curve of the BL Lacertae type blazar OJ287 with time-dependent multi-waveband flux and linear polarization observations and submilliarcsecond-scale p…
