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…
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…
In Search of Evidence for Toroidal B Fields Associated with the Jets of AGN
Denise C. Gabuzda, Eamonn Murray
Evidence is mounting that many of the transverse jet B fields observed in BL Lac objects on parsec scales represent the dominant toroidal component of the intrinsic jet B fields. I…
Where has all the polarization gone?
E. Middelberg, A. L. Roy, U. Bach +2
We have observed the five radio galaxies NGC1052, NGC4261, Hydra A, Centaurus A and Cygnus A with polarimetric VLBI at 15 GHz to look for possible Faraday rotation in foreground ab…
Polarimetric VLBI observations of 0735+178
I. Agudo, J. L. Gomez, D. C. Gabuzda +5
We present a new centimeter polarimetric VLBI image of the BL Lac object 0735+178. This source exhibits one of the most pronounced curvatures observed in jets of AGNs, with two sha…
The core-jet structure of the JVAS gravitational lens B1030+074
E. Xanthopoulos, M. Norbury, A. Karidis +6
We present results from VLBA+Effelsberg 1.7 GHz, VLBA 8.4 GHz and VLBA 15 GHz observations of the JVAS gravitational lens system B1030+074. The VLBA+Effelsberg 1.7 GHz data with 3…
