Parsec-Scale Jet Behavior of the Quasar 3C 454.3 during the High Gamma-Ray States in 2009 and 2010
S. G. Jorstad, A. P. Marscher, M. Joshi +7
We analyze total and polarized intensity images of the quasar 3C 454.3 obtained monthly with the VLBA at 43 GHz within the ongoing Boston U. monitoring program of gamma-ray blazars…
VLBA monitoring of Mrk 421 at 15 and 24 GHz during 2011
R. Lico, M. Giroletti, M. Orienti +13
We present a preliminary analysis of new high resolution radio observations of the nearby TeV blazar Markarian 421 (z=0.031). This study is part of an ambitious multifrequency camp…
Relation between Events in the Millimeter-wave Core and Gamma-ray Outbursts in Blazar Jets
A. P. Marscher, S. G. Jorstad, I. Agudo +2
Analysis of comprehensive monitoring of 34 gamma-ray bright quasars, BL Lac objects, and radio galaxies reveals a close connection between events in the millimeter-wave emission im…
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…
