    • CO observations of high-z radio galaxies MRC 2104-242 and MRC 0943-242 : Spectral-line performance of the Compact Array Broadband Backend 

      Emonts, B.H.C.; Norris, R.P.; Feain, I.; Miley, G.; Sadler, E.M.; Villar-Martin, M.; Mao, M.Y.; Oosterloo, T.A.; Ekers, R.D.; Stevens, J.B.; Wieringa, M. H.; Coppin, Kristen; Tadhunter, C.N. (2011-07-01)
      We present the first 7-mm observations of two high-redshift, Lyα-bright radio galaxies (MRC 2104-242 and MRC 0943-242) performed with the 2 × 2GHz instantaneous bandwidth of the Compact Array Broadband Backend (CABB) at ...

    • Highly polarized structures in the near-nuclear regions of Cygnus A: intrinsic anisotropy within the cones 

      Tadhunter, C.N.; Sparks, W.; Axon, D.J.; Bergeron, L.; Jackson, N.; Packham, C.; Hough, J.; Robinson, A.; Young, S. (2000)
      We present near-IR imaging polarimetry observations of the nucleus of Cygnus A, taken with the NICMOS camera of the HST at a wavelength of 2.0μm. These maps reveal a highly collimated region of polarized emission straddling ...

    • A large-scale shock surrounding a powerful radio galaxy? 

      Croston, J.H.; Hardcastle, M.J.; Mingo, B.; Evans, D.A.; Dicken, D.; Morganti, R.; Tadhunter, C.N. (2011)
      We report Chandra evidence for a 200 kpc scale shock in the cluster surrounding the powerful radio galaxy 3C444. Our 20 ks observation allows us to identify a clear surface brightness drop around the outer edge of the radio ...

    • Near-infrared imaging polarimetry of Cygnus A 

      Packham, C.; Young, S.; Hough, J.; Tadhunter, C.N.; Axon, D.J. (1998)
      We present a 2.2-μm polarization image of the nuclear regions of Cygnus A. The degree of polarization in the central 1 arcsec is (4.1±0.50) per cent, at a position angle of (23.6±3.6)°, approximately perpendicular to the ...

    • An X-ray survey of the 2 Jy sample - II. X-ray emission from extended structures 

      Mingo, B.; Hardcastle, M. J.; Ineson, J.; Mahatma, V.; Croston, J. H.; Dicken, D.; Evans, D. A.; Morganti, R.; Tadhunter, C.N. (2017-09-21)
      The 2 Jy sample is a survey of radio galaxies with flux densities above 2 Jy at 2.7 GHz. As part of our ongoing work on the southern subset of 2 Jy sources, in paper I of this series we analysed the X-ray cores of the ...
