IR Imaging Polarimetry of the Nuclear Regions of CEN A

Aperture polarimetry of the nucleus of Cen A (Bailey et al. 1986) revealed a very red polarized source present in the K and L bands which was interpreted as a blazar type nucleus. To study this region in more detail we observed it on 1993 May 5 using the IRIS IR camera together with a polarimetry system developed at the University of Hertfordshire.
