        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, ...

        Modeling New Spectropolarimetry Data for the BN Object 

        Messinger, D.W.; Roberge, W.G.; Whittet, D.C.B.; Chrysostomou, A.; Hough, J. (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 

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

        Nartallo, R.; Gear, W.K.; Murray, A.G.; Hobson, E.I.; Hough, J. (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 

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

        Hough, J. (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 ...

        Millimeter polarimetry of star-forming regions : magnetic field structure and low mass stars 

        Tamura, M.; Hayashi, S.; Hough, J. (1995)
        We have measured polarization of the 1.1 mm and 0.8 mm continuum emission for 3 pre-T Tauri stars and 2 T Tauri stars. Positive detections were made for NGC 1333 IRAS 4 and IRAS 16293-2422, while L1551 IRS 5 and HL Tau ...

        High Resolution Studies of Molecular Hydrogen by Means of Near-Infrared Fabry-Perot Imaging 

        Chrysostomou, A.; Burton, M.; Axon, D.J.; Brand, P.W.J.L.; Hough, J.; Bland-Hawthorn, J.; Geballe, T. (Astronomical Society of the Pacific, 1995)
        We present a study of the velocity profiles of the v=1-0 S(1) transition of molecular hydrogen (H2) towards the star forming region of OMC-1. A three dimensional data cube is presented which displays the spatial distribution ...

        A model for the infrared continuum spectrum of NGC 1068 

        Efstathiou, A.; Hough, J.; Young, S. (1995)
        We present a model for the nuclear infrared (IR) continuum spectrum of the Seyfert galaxy NGC 1068. The torus emission is modelled in terms of the tapered disc models of Efstathiou & Rowan-Robinson, which give a good fit ...
