Evidence for an Obscured Broadline Region in the Early Type Radio Galaxy IC5063
Inglis, M.D.; Brindle, C.; Hough, J.; Young, S.; Axon, D.J.; Bailey, J.; Ward, M.J. (1993)We report the detection of strong, broad Hα emission seen in polarized flux from the early-type radio galaxy IC 5063. This suggests that the galaxy has a broad-line region which is obscured from our direct view, with the ... -
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 ... -
Near-IR spectropolarimetry and modeling of NGC 1068
Young, S.; Hough, J.; Axon, D.J.; Bailey, J.; Ward, M.J. (1995)We present new spectropolarimetric data for NGC 1068, including, for the first time, coverage in the near-IR. Using these, and other previously published data, we develop a scattering model for NGC 1068, using NGC 5548 for ... -
Near-IR Spectropolarimetry of NGC 1088
Young, S.; Hough, J.; Bailey, J.; Axon, D.J.; Ward, M.J. (Astronomical Society of the Pacific, 1994)The current unified model of Seyfert galaxies, as proposed by Antonucci and Miller (1985), has most, if not all, Seyfert 2 galaxies hosting a Seyfert 1 type nucleus in their cores. The broad lines from the type 1 nucleus ... -
The obscured BLR in the radio galaxy 3C 234
Young, S.; Axon, D.J.; Hough, J.; Fabian, A.C.; Ward, M.J. (1998)We present spectropolarimetric observations of the radio galaxy 3C 234 at optical and, for the first time, near-IR wavelengths. In agreement with previous observations we detect broad Hα in total and polarized flux, ... -
An optical and near-infrared polarization survey of Seyfert and broad-line radio galaxies. 1 : statistical properties
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Ward, M.J.; Sparks, W.; McLean, I. (1990)The present broad-band and near-IR flux density and polarization measurements of a sample of 71 Seyfert galaxies and three broad-line radio galaxies confirms earlier indications that the polarization of Seyferts is generally ... -
An optical and near-infrared polarization survey of Seyfert and broad-line radio galaxies. 2 : the wavelength dependence of polarization
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Ward, M.J.; Sparks, W.; McLean, I. (1990)We discuss the wavelength dependence (0.44-2.2 micron) of polarization of the sample of 71 Seyfert and three broad-line radio galaxies presented in Paper I. For four galaxies, 3A 0557-353, Fairall 51, IC 4329A and NGC 3753, ... -
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 ... -
The polarization of NGC 1068
Bailey, J.; Axon, D.J.; Hough, J.; Ward, M.J.; McLean, I.; Heathcote, S.R. (1988)Broad-band polarimetry of NGC 1068 over the wavelength range 0.36 - 4.8 μm is presented, together with high-resolution spectropolarimetry of the Hβ, [O III] and Hα, [N II] regions of the spectrum. The authors recognize ... -
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, ... -
Spatially Resolved Spectropolarimetry of NGC 1068
Inglis, M.D.; Young, S.; Hough, J.; Axon, D.J.; Bailey, J.; Ward, M.J. (Astronomical Society of the Pacific, 1994)A turning point in the study of AGN was the discovery of broad hydrogen lines seen in polarized light in the nucleus of NGC 1068 (Antonucci and Miller 1985). A model was developed whereby the scatterers responsible for ... -
Spectropolarimetry of the ultraluminous infrared galaxy IRAS 110548-1131
Young, S.; Hough, J.; Bailey, J.; Axon, D.J.; Ward, M.J. (1993)From spectropolarimetric observations of the galaxy IRAS 110548-1131 we report very strong, broad H-alpha emission (FWHM 7600 km/s) in the polarized flux spectrum. This suggests that IRAS 110548-1131 has an obscured ... -
The variable infrared source near HH100
Axon, D.J.; Allen, D.; Bailey, J.; Hough, J.; Ward, M.J.; Jameson, R.F. (1982)Photometric observations are presented which confirm the high variability, of up to 2.5 mag at K, of the IR source associated with the Herbig-Haro object HH100, and it is suggested that such a large variation must be a ...
