Multi-frequency Polarization Imaging of Blazars with Cyclic Activity
T. B. Pyatunina, D. C. Gabuzda, S. G. Jorstad +3
Results of multi-frequency VLBA polarization imaging for sources showing evidence of quasi-periodic variations in their total flux density are discussed. Possible origins of the ob…
Analysis of Strong Outbursts in Selected Blazars from the Metsahovi and UMRAO Monitoring Databases
T. B. Pyatunina, N. A. Kudryavtseva, D. C. Gabuzda +4
Frequency-dependent time lags for strong outbursts in four gamma-blazars are determined. The time lags for two adjacent outbursts in 2230+114 are correlated with the outburst ampli…
Intermediate Scale Structures in BL Lac objects
C. Reynolds, T. V. Cawthorne, D. C. Gabuzda
The parsec-scale total intensity structures of BL Lac objects share many characteristics with quasars: e.g. well-collimated jets and superluminal motion. However, the jets of BL La…
Polarization and energy content of parsec scale AGN jets
Maxim Lyutikov, Vladimir I. Pariev, Denise C. Gabuzda
Most of energy carried by relativistic AGN jets remains undetected until hundreds of kiloparsecs where interaction with intergalactic medium produces hot spots. The jet's hidden en…
Evidence for Toroidal B-Field Structures in BL Lac Objects
D. C. Gabuzda, E. Murray, P. Cronin
If the transverse jet B fields observed in BL Lac objects on parsec scales represent the toroidal component of the jet B fields, this should give rise to rotation-measure gradients…
