      We present results from a 40 ks XMM-Newton observation of the X-ray filament coincident with the southeast edge of the Centaurus A Northern Middle Radio Lobe (NML). We find that the X-ray filament consists of five spatially ...

    • Jet interactions with a giant molecular cloud in the Galactic centre and ejection of hypervelocity stars 

      Silk, J.; Antonuccio-Delogu, V.; Dubois, Y.; Gaibler, V.; Haas, M.~R.; Khochfar, S.; Krause, Martin (2012-09-21)
      The hypervelocity OB stars in the Milky Way Galaxy were ejected from the central regions some 10-100 million years ago. We argue that these stars, as well as many more abundant bound OB stars in the innermost few parsecs, ...

    • Jet/Environment Interactions in Low-Power Radio Galaxies 

      Croston, J.H. (Astronomical Society of the Pacific, 2008)
      The interactions between low-power radio galaxies and their environments are thought to play a crucial role in supplying energy to offset cooling in the centres of groups and clusters. Such interactions are also important ...

      Krause, M.~G.~H. (Memorie della Societa Astronomica Italiana, 2008-06-06)
      Jets are observed to stir up multiphase turbulence in the interstellar medium as well as far beyond the host galaxy. Here we present detailed simulations of this process. We evolve the hydrodynamics equations with optically ...

    • The jets in 3C 296 

      Hardcastle, M.J.; Alexander, P.; Pooley, G.G.; Riley, J.M. (1997)
      We present observations made with the VLA at 1.5 and 8.4 GHz of the nearby FRI radio galaxy 3C296. The most recent models of FRI radio galaxies suggest that sub- stantial deceleration must take place in their jets, with ...

    • Jets, plumes and hotspots in the wide-angle tail source 3C 130 

      Hardcastle, M.J. (1998)
      I present 1.5- and 8.4-GHz observations with all configurations of the NRAO VLA of the wide-angle tail source 3C130. The source has a pair of relatively symmetrical, well- collimated inner jets, one of which terminates in ...

      Short, G.; Lenga, R.A. (2002)
      In February 2001 the British government announced its commitment to increase the number of schools run by the churches and other religious groups where there was 'clear local demand from parents and the community'. The ...

    • Jim Crace, quarantine, and the Dawkins delusion 

      Holderness, G. (2010)
      Jim Crace's novel Quarantine purports to be a text of 'post-Dawkins scientific atheism'. It re-sets the mystical gospel story of the Temptation in the Wilderness into a materialist universe where only the laws of nature ...
