Simultaneous UBVRIJK photometric and polarimetric observations of PQ Gem
(1997)
We present simultaneous UBVRIJK observations of the intermediate polar PQ Gem (RE J0751+14) obtained on 1993 February 18 and 19 using the Hatfield Polarimeter on UKIRT. The light curves show double- peaked modulation on ...
Polarization Properties of Active Galactic Nuclei
(Astronomical Society of the Pacific, 1997)
One of the main uses of polarimetry over the last decade has been to identify the nature of AGN that are normally hidden from direct view by an optically and geometrically thick torus, and thereby to unify different classes ...
Scattered broad optical lines in the polarized flux spectrum of the FR II galaxy 3C 321
(1996)
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, ...
Modeling New Spectropolarimetry Data for the BN Object
(Astronomical Society of the Pacific, 1996)
New spectropolarimetry data taken for the BN object include many previously unobserved features. Among these are a possible polarization reversal at the short wavelength end of the ice feature and a rotation in the position ...
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 ...
Submillimetre Polarimetry of Blazars
(Astronomical Society of the Pacific, 1996)
We report on preliminary results from the first monitoring campaign of the submillimetre polarization of a sample of Blazars. The observations have been carried out with the James Clerk Maxwell Telescope between 1991 and 1994.
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 of External Galaxies
(Astronomical Society of the Pacific, 1996)
This review presents results to date on the wavelength dependence of interstellar polarization (ISP) in other galaxies. A number of different techniques are discussed, and galaxy types range from those similar to the Milky ...
The nuclear torus in the active galaxy NGC 1068
(1996)
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 ...
Magnetic Fields in Star Forming Regions - Near-Infrared and Submillimeter Approaches
(Astronomical Society of the Pacific, 1996)
In order to study the magnetic field structure in star forming regions on various scales, we have been conducting both near-infrared and submillimeter polarimetry toward nearby molecular clouds. The near-infrared approach ...
