Are Spine--Sheath Polarization Structures in the Jets of Active Galactic Nuclei Associated with Helical Magnetic Fields?
Denise C. Gabuzda, Andrea Reichstein, Eamonn L. O'Neill
One possible origin for polarization structures across jets of Active Galactic Nuclei (AGNs) with a central "spine" of orthogonal magnetic field and a "sheath" of longitudinal magn…
The environment of AGNs and the activity degree of their surrounding galaxies
W. Kollatschny, A. Reichstein, M. Zetzl
Aims. We present results of a comprehensive spectral study on the large-scale environment of AGNs based on Sloan Spectroscopic Survey data. Methods. We analyzed the spectra of gala…
The Use of Faraday Rotation Sign Maps as a Diagnostic for Helical Jet Magnetic Fields
Andrea Reichstein, Denise Gabuzda
We present maps of the sign of the Faraday Rotation measure [sign(RM)] obtained from multi-frequency radio observations on the Very Long Baseline Array (VLBA). Many of the Active G…
Studying magnetic fields in several parsec-scale AGN jets using Faraday Rotation
Andrea Reichstein, Denise Gabuzda
We present multi-frequency radio observations from the Very Long Baseline Array (VLBA) of selected AGN that seem to have a B-field structure with a central "spine" of B-field ortho…
