Highly polarized structures in the near-nuclear regions of Cygnus A: intrinsic anisotropy within the cones?

C. N. Tadhunter, W. Sparks, D. J. Axon +6

We present near-IR imaging polarimetry observations of the nucleus of Cygnus A, taken with the NICMOS camera of the HST at a wavelength of 2.0 microns.These maps reveal a highly co…
