    • 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 ...

    • A Polarization Flare in 3C 273: A Clue to Jet Physics 

      Cross, L.L.; Wills, B.; Hough, J.; Bailey, J. (Astronomical Society of the Pacific, 2001)
      We present UBVRIJHK polarization and flux density observations of the quasar 3C 273 obtained during a time of outburst over two weeks in 1988 February. We have modelled these data with two power law components, each with ...

    • Ring Structure and Warp of NGC 5907: Interaction with Dwarf Galaxies 

      Shang, Z.; Zheng, Z.; Brinks, E.; Chen, J.; Burstein, D.; Su, H.W.; Byun, Y.; Deng, L.; Deng, Z.; Fan, X.; Jiang, Z.; Li, Y.; Lin, W.; Ma, F.; Sun, W.; Wills, B.; Windhorst, R.A.; Wu, H.; Xia, X.; Xu, W.; Xue, S.; Yan, H.; Zhou, X.; Zhu, J.; Zou, Z. (1998)
      The edge-on, nearby spiral galaxy NGC 5907 has long been used as the prototype of a “noninteracting” warped galaxy. We report here the discovery of two interactions with companion dwarf galaxies that substantially change ...

    • 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, ...
