Near-infrared and millimetre polarimetry of CEN A
(1996)
We present near-infrared polarization images of the nuclear region of CenA, and millimetre polarimetry of the nucleus. In the near-infrared the polarization vectors mainly lie along the dust lane, with the polarization ...
A Model for the Infrared Polarization of NGC 1068
(Astronomical Society of the Pacific, 1996)
We present a method for calculating the polarization due to absorption and emission by aligned grains distributed in a disk or a torus. The temperature distribution in the torus is calculated self-consistently with the ...
Powering the Broad H alpha Line in BL Lacertae
(Astronomical Society of the Pacific, 1996)
Polarimetry and the torus
(1996)
While the torus plays an obvious role in blocking direct light, and thus increasing the observed polarization from scattering, its role in directly producing polarized flux is less clear. Contributions to the infrared ...
Polarimetry and modelling of narrow-line active galaxies
(1996)
We present optical spectropolarimetry along with optical and infrared broad-band filter polarimetry of selected warm [f(25 μm)/f(60 μm)>=0.3] IRAS galaxies and other known Seyfert 2 galaxies. Broad lines in polarized flux ...
