    • High-energy particle acceleration at the radio-lobe shock of Centaurus A 

      Croston, J.H.; Kraft, R.P.; Hardcastle, M.J.; Birkinshaw, M.; Worrall, D.M.; Nulsen, P.E.J.; Penna, R.F.; Sivakoff, G.R.; Jordan, R.; Brassington, Nicola; Evans, D.A.; Forman, W.R.; Gilfanov, M.; Goodger, Joanna; Harris, W.E.; Jones, C.; Juett, A.M.; Murray, S.S.; Raychaudhury, S.; Sarazin, C.L.; Voss, R.; Woodley, K.A. (2009)
      We present new results on the shock around the south-west radio lobe of Centaurus A using data from the Chandra Very Large Programme observations (740 ks total observing time). The X-ray spectrum of the emission around the ...

    • Long-term monitoring of the dynamics and particle acceleration of knots in the jet of Centaurus A 

      Goodger, Joanna; Hardcastle, M.J.; Croston, J.H.; Kraft, R.P.; Birkinshaw, M.; Evans, D.A.; Jordan, A.; Nulsen, P.E.J.; Sivakoff, G.R.; Worrall, D.M.; Brassington, Nicola; Forman, W.R.; Gilfanov, M.; Jones, C.; Murray, S.S.; Raychaudhury, S.; Sarazin, C.L.; Voss, R.; Woodley, K.A. (2010)
      We present new and archival multi-frequency radio and X-ray data for Centaurus A obtained over almost 20 years at the Very Large Array and with Chandra, with which we measure the X-ray and radio spectral indices of jet ...

    • Luminosity functions of LMXBs in Centaurus A: globular clusters versus the field 

      Voss, R.; Gilfanov, M.; Sivakoff, G.R.; Kraft, R.P.; Jordan, A.; Raychaudhury, S.; Birkinshaw, M.; Brassington, Nicola; Croston, J.H.; Evans, D.A.; Forman, W.R.; Hardcastle, M.J.; Harris, W.E.; Jones, C.; Juett, A.M.; Murray, S.S.; Sarazin, C.L.; Woodley, K.A.; Worrall, D.M. (2009)
      We study the X-ray luminosity function (XLF) of low-mass X-ray binaries (LMXB) in the nearby early-type galaxy Centaurus A, concentrating primarily on two aspects of binary populations: the XLF behavior at the low-luminosity ...

    • Luminosity functions of LMXBs in different stellar environments 

      Zhang, Z.; Gilfanov, M.; Voss, R.; Sivakoff, G. R.; Kraft, R. P.; Brassington, Nicola; Kundu, A.; Jordan, A.; Sarazin, C. (2011-09)
      Aims. Based on the archival data from the Chandra observations of nearby galaxies, we study different sub populations of low-mass X-ray binaries (LMXBs) - dynamically formed systems in globular clusters (GCs) and in the ...

    • 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 ...
