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…

Real vs. simulated relativistic jets
J. L. Gomez, J. M. Marti, I. Agudo +3
Intensive VLBI monitoring programs of jets in AGN are showing the existence of intricate emission patterns, such as upstream motions or slow moving and quasi-stationary componentes…
