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…

86 GHz polarimetry of OVV1633+382 after a major mm flare
B. W. Sohn, T. P. Krichbaum, I. Agudo +4
The 18 mag QSO 1633+382 (4C38.41, z=1.807) showed a very pronounced outburst in 2001/2002. With a peak amplitude of more than 9 Jy at 90GHz, this flare was brighter than any known…
