    The jet and circumnuclear environment of 3C 293 

    Floyd, David; Perlman, Eric; Leahy, J. Patrick; Beswick, Rob; Jackson, Neal; Sparks, William; Axon, David; O’Dea, Christopher (Astrophysical Journal, 2006-03-01)
    We present the new HST near-infrared polarimetry, broad and narrow-band imaging, and MERLIN 4.5GHz Multi-Frequency Synthesis radio imaging of 3C 293, a unique radio galaxy whose host is an obvious merger remnant, in an ...

    The warped nuclear disk of radio galaxy 3C 449 

    Tremblay, Grant; Quillen, Alice; Floyd, David; Noel-Storr, Jacob; Baum, Stefi; Axon, David; O'Dea, Christopher; Chiaberge, Marco; Macchetto, Duccio; Sparks, William; Miley, George; Capetti, Alessandro; Madrid, Juan; Perlman, Eric (Astrophysical Journal, 2006)
    Among radio galaxies containing nuclear dust disks, the bipolar jet axis is generally observed to be perpendicular to the disk major axis. The FR I radio source 3C 449 is an outlier to this statistical majority, as it ...

    BIMA millimeter-wave observations of the core-jet and molecular gas in the FR I radio galaxy NGC 3801 

    Das, Mousumi; Vogel, Stuart; Kleijn, Gijs; O’Dea, Christopher; Baum, Stefi (Astrophysical Journal, 2005-08-20)
    We present BIMA 3 mm observations of the radio continuum source and the molecular gas disk in the radio loud Fanaroff & Riley Type I (FR I) galaxy NGC 3801. We have detected a continuum source in the nucleus and determined ...

    Equatorial scattering and the structure of the broad-line region in Seyfert nuclei: Evidence for a rotating disc 

    Smith, James; Robinson, Andrew; Young, Stuart; Axon, David; Corbett, Elizabeth (Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2005-05)
    We present detailed scattering models confirming that distinctive variations in polarization across the broad Halpha line, which are observed in a significant fraction of Seyfert 1 galaxies, can be understood in terms of ...

    High resolution studies of radio sources in the Hubble Deep and Flanking Fields 

    Muxlow, Tom; Richards, Anita; Garrington, Simon; Wilkinson, Peter; Anderson, Bryan; Richards, Eric; Axon, David; Fomalont, Edward; Kellermann, Kenneth; Partridge, Bruce; Windhorst, Rogier (Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2005-04)
    Eighteen days of MERLIN data and 42 hours of A-array VLA data at 1.4 GHz have been combined to image a 10-arcmin field centred on the Hubble Deep and Flanking Fields (HDF and HFF). A complete sample of 92 radio sources ...

    Seyferts on the edge: Polar scattering and orientation-dependent polarization in Seyfert 1 nuclei 

    Smith, James; Robinson, Andrew; Alexander, David; Young, Stuart; Axon, David; Corbett, Elizabeth (Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2004-05)
    We have identified 12 Seyfert 1 galaxies that exhibit optical polarization spectra similar to those of Seyfert 2 galaxies in which polarized broad-lines are detected. We present new spectropolarimetric observations of 3 ...

    Spectroscopy of the near-nuclear regions of Cygnus A: Estimating the mass of the supermassive black hole 

    Tadhunter, Clive; Marconi, Alessandro; Axon, David; Wills, Karen; Robinson, TG; Jackson, Neal (Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2003-07)
    We use a combination of high spatial resolution optical and near-IR spectroscopic data to make a detailed study of the kinematics of the NLR gas in the near-nuclear regions of the powerful, FRII radio galaxy Cygnus A ...

    A spectropolarimetric atlas of Seyfert 1 galaxies 

    Smith, James; Young, Stuart; Robinson, Andrew; Corbett, Elizabeth; Giannuzo, Ester; Axon, David; Hough, James (Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2002-09-27)
    We present optical spectropolarimetry of the nuclei of 36 Seyfert 1 galaxies, obtained with the William Herschel and the Anglo–Australian Telescopes from 1996 to 1999. In 20 of these, the optical emission from the active ...

    HI absorption in the gigamaser galaxy TXS 2226-184 and the relation between HI absorption and water emission 

    Taylor, Gregory; Peck, Alison; Henkel, Christian; Falcke, Heino; Mundell, Carole; O'Dea, Christopher; Baum, Stefi; Gallimore, Jack (American Astronomical Society, 2002-07-20)
    We report on the discovery of H i in absorption toward the gigamaser galaxy TXS 2226-184 using the Very Large Array. The absorption appears to consist of two components—one with a width of 125 km s^-1 and one broader (420 ...

    A NICMOS imaging study of high-z quasar host galaxies 

    Kukula, Marek; Dunlop, James; McClure, Ross; Miller, Lance; Percival, Will; Baum, Stefi; O'Dea, Christopher (Blackwell Publishing, 2001-10)
    We present the first results from a major Hubble Space Telescope programme designed to investigate the cosmological evolution of quasar host galaxies from z~=2 to the present day. Here we describe J and H-band NICMOS ...
