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…
The extreme flare in III Zw 2: Evolution of a radio jet in a Seyfert galaxy
A. Brunthaler, H. Falcke, G. C. Bower +3
A very detailed monitoring of a radio flare in the Seyfert I galaxy III Zw 2 with the VLA and the VLBA is presented. The relative astrometry in the VLBA observations was precise on…
An extremely curved relativistic jet in PKS 2136+141
T. Savolainen, K. Wiik, E. Valtaoja +1
We report the discovery of an extremely curved jet in the high frequency peaking GPS quasar PKS 2136+141. Our multi-frequency VLBA images show a bending jet making a turn-around of…
Oblique Polarization Structures in AGN and QSO Radio Jets
H. D. Aller, M. F. Aller, P. A. Hughes
We interpret the linear polarization structures observed in extragalactic radio sources, even those oriented at oblique angles to the jet flows, to be due to oblique, relativistic…
Centimeter-band Variability in GPS Sources
M. F. Aller, H. D. Aller, P. A. Hughes +1
Monitoring results are presented for the Stangellini 1 Jy GHz-peaked-spectrum source sample, illustrating that several members exhibit variability in total flux and/or linear polar…
Broadband Spectra and Variability of BL Lacertae in 2000
M. Boettcher, H. D. Aller, M. F. Aller +6
We have organized an extensive multiwavelength campaign on BL Lacertae in the second half of 2000. Simultaneous or quasi-simultaneous observations were taken at radio frequencies,…
