The nuclear torus in the active galaxy NGC 1068
We present near-infrared polarized images of the active galaxy NGC 1068. At these wavelengths, the counter-cone is observed in scattered light. At H (1.64 μm) we detect an absorption band across the counter-cone, which we ...
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 ...
Scattered broad optical lines in the polarized flux spectrum of the FR II galaxy 3C 321
The authors present optical/infrared broad-band filter polarimetry and optical spectropolarimetry of the powerful FR II galaxy 3C 321. The latter observations reveal a scattered broad component to the Hα emission line, ...
Polarimetry and modelling of narrow-line active galaxies
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 ...
Polarimetry and the torus
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 ...
