MEM imaging of multi-wavelength VLBA polarisation observations of Active Galactic Nuclei
Colm P. Coughlan, Denise C. Gabzuda
We have developed a C++ implementation of the Maximum Entropy Method (MEM) suitable for deconvolving VLBI polarisation data. The first results of this implementation are presented…
Connecting Magnetic Towers with Faraday Rotation Gradients in Active Galactic Nuclei Jets
Mehreen Mahmud, Colm P. Coughlan, Eoin Murphy +2
The idea that systematic Faraday Rotation gradients across the parsec-scale jets of AGNs can reveal the presence of helical magnetic (B) fields has been around since the early 1990…
Analysing the Transverse Structure of the Relativistic Jets of AGN
E. G. Murphy, T. V. Cawthorne, D. C. Gabuzda
This paper describes a method of fitting total intensity and polarization profiles in VLBI images of astrophysical jets to profiles predicted by a theoretical model. As an example,…
