Optical and near-infrared spectropolarimetry of the infrared-luminous galaxy IRAS 23060+0505

Young, S.; Hough, J.; Axon, D.J.; Ward, M.J.; Bailey, J. (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 ...

Near-infrared and millimetre polarimetry of CEN A

Packham, C.; Hough, J.; Young, S.; Chrysostomou, A.; Bailey, J.; Axon, D.J.; Ward, M.J. (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 ...

3 MU M Spectropolarimetry of 1120 Ice in Young Stellar Objects

Chrysostomou, A.; Hough, J.; Messinger, D.W.; Whittet, D.C.B.; Aitken, D.; Hoche, P.F. (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 ...

The nuclear torus in the active galaxy NGC 1068

Young, S.; Packham, C.; Hough, J.; Efstathiou, A. (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

Tamura, M.; Hayashi, S.; Itoh, Y.; Hough, J.; Chrysostomou, A. (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 ...

The appearance of broad H alpha in BL Lacertae

Corbett, E.A.; Robinson, A.; Axon, D.J.; Hough, J.; Jeffries, R.D.; Thurston, M.R.; Young, S. (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, ...

A Model for the Infrared Polarization of NGC 1068

Efstathiou, A.; Hough, J.; McCall, A.; Young, S. (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 ...

Dust in a Hostile Environment: Interstellar Dust in the Line of Sight to HD62542

Magalhaes, A.M.; Rodrigues, C.V.; Meade, M.; Code, A.D.; Nordsieck, K.H.; Anderson, C.M.; Bailey, J.; Hough, J.; Wheatley, P.J. (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 ...

Powering the Broad H alpha Line in BL Lacertae

Corbett, E.A.; Robinson, A.; Hough, J.; Young, S.; Axon, D.J. (Astronomical Society of the Pacific, 1996)

Scattered broad optical lines in the polarized flux spectrum of the FR II galaxy 3C 321

Young, S.; Hough, J.; Efstathiou, A.; Wills, B.; Axon, D.J.; Bailey, J.; Ward, M.J. (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, ...
