High resolution VLBI polarisation imaging of AGN with the Maximum Entropy Method
Colm P. Coughlan, Denise C. Gabuzda
Radio polarisation images of the jets of Active Galactic Nuclei (AGN) can provide a deep insight into the launching and collimation mechanisms of relativistic jets. However, even a…
A GMRT survey of regions towards the Taurus Molecular Cloud at 323 and 608 MHz
Rachael E. Ainsworth, Colm P. Coughlan, David A. Green +2
We present observations of three active sites of star formation in the Taurus Molecular Cloud complex taken at 323 and 608 MHz (90 and 50 cm, respectively) with the Giant Metrewave…
Describing the Uncertainties in VLBI Images
Colm P. Coughlan, Denise C. Gabuzda
We are investigating a new approach to modelling uncertainties in individual pixels of Very Long Baseline Interferometry (VLBI) intensity (Stokes I, Q, U) images. Comparison of dis…
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…
