    • Spectral ageing in the lobes of FR-II radio galaxies : New methods of analysis for broad-band radio data 

      Harwood, J.J.; Hardcastle, M.J.; Croston, J.H.; Goodger, J.L. (2013-11-01)
      The broad-bandwidth capabilities of next generation telescopes such as the Jansky Very Large Array (JVLA) mean that the spectrum of any given source varies significantly within the bandwidth of any given observation. ...

    • Spectral properties of X-ray binaries in Centaurus A 

      Burke, M.J.; Raychaudhury, S.; Kraft, R.P.; Forman, W.R.; Jones, C.; Murray, S.S.; Birkinshaw, M.; Evans, D.A.; Jordán, A.; Worrall, D.M.; Maccarone, T. J.; Croston, J.H.; Brassington, Nicola; Hardcastle, M.J.; Goodger, J.L.; Kainulainen, J.; Woodley, K.A.; Sivakoff, G.R.; Gilfanov, M.; Zhang, Z.; Sarazin, C.L.; Voss, R. (2013-04-01)
      We present a spectral investigation of X-ray binaries (XBs) in NGC 5128 (Cen A), using six 100 ks Chandra observations taken over two months in 2007. We divide our sample into thermally and non-thermally dominated states ...

    • A transient sub-Eddington black hole X-ray binary candidate in the dust lanes of Centaurus A 

      Burke, M.J.; Raychaudhury, S.; Kraft, R.P.; Forman, W.R.; Jones, C.; Murray, S.S.; Evans, D.A.; Jordán, A.; Brassington, Nicola; Hardcastle, M.J.; Goodger, J.L.; Sivakoff, G.R.; Woodley, K.A.; Kainulainen, J.; Birkinshaw, M.; Worrall, D.M.; Croston, J.H.; Gilfanov, M.; Zhang, Z.; Sarazin, C.L.; Voss, R. (2012-04-20)
      We report the discovery of a bright X-ray transient CXOU J132527.6-430023 in the nearby early-type galaxy NGC5128. The source was first detected over the course of five Chandra observations in 2007, reaching an unabsorbed ...
