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 ...
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.
3 MU M Spectropolarimetry of 1120 Ice in Young Stellar Objects
(Astronomical Society of the Pacific, 1996)
Spectropolarimetry of the water-ice feature at 3.1um towards a number of YSOs is presented. The data show that excesses of polarization and changes in position angle across the feature are common. The polarization excess ...
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 ...
Optical and near-infrared spectropolarimetry of the infrared-luminous galaxy IRAS 23060+0505
(1996)
We present optical and near-IR spectropolarimetry of the type 2 infrared-luminous galaxy IRAS 23060+0505, which clearly shows both broad Hα and Paalpha in polarized flux. The full widths at half maximum (FWHM) of these ...
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, ...
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 ...
The appearance of broad H alpha in BL Lacertae
(1996)
We present optical spectropolarimetry confirming Vermeulen et al.'s recent discovery of a broad Hα emission line in BL Lacertae. This feature, which is present at about the same strength in spectra taken two days apart, ...
Dust in a Hostile Environment: Interstellar Dust in the Line of Sight to HD62542
(Astronomical Society of the Pacific, 1996)
HD 62542 is situated in a line of sight toward a ridge of dark matter in the Gum Nebula. That region is under the influence of UV radiation and stellar winds from hot stars. We use for the first time interstellar polarization ...
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 ...
