  • Wave-vector analysis of metallic surface energy 

    Rasolt, M.; Malmstrom, G.; Geldart, D. J. W. (1979-10/15)
    The exchange and correlation energy of a nonuniform electronic system can be decomposed into contributions of different wave-vector fluctuations. Both the long- and short-wavelength contributions to this energy can be ...

  • Wave-vector decomposition of the exchange and correlation contributions to a metallic surface energy 

    Rasolt, M.; Geldart, D. J. W. (1980-04/15)
    The authors decompose the lowest-order nonlocal corrections to the local-density approximation to the exchange and correlation component of the metallic surface energy in terms its wave-vector components. Comparison with ...

  • Weighing the Black Holes in z~2 Submillimeter-Emitting Galaxies Hosting Active Galactic Nuclei 

    Alexander, D. M.; Brandt, W. N.; Smail, I.; Swinbank, A. M.; Bauer, F. E.; Blain, A. W.; Chapman, S. C.; Coppin, K. E. K.; Ivison, R. J.; Menendez-Delmestre, K. (2008-05-01)
    We place direct observational constraints on the black-hole masses of the cosmologically important z~2 submillimeter-emitting galaxy (SMG; f850>4mJy) population, and use measured host-galaxy masses to explore their ...

  • Westphal-MMD11: An interacting, submillimeter luminous Lyman break galaxy 

    Chapman, S. C.; Shapley, A.; Steidel, C.; Windhorst, R. (2002-6-10)
    We present new Hubble Space Telescope, high-resolution optical imaging of the submm luminous Lyman-break galaxy, Westphal-MMD11, an interacting starburst at z=2.979. The new imaging data, in conjunction with re-analysis ...

  • The X-ray Spectral Properties of SCUBA Galaxies 

    Alexander, D. M.; Bauer, F. E.; Chapman, S. C.; Smail, I.; Blain, A. W.; Brandt, W. N.; Ivison, R. J. (2005-10-20)
    Deep SCUBA surveys have uncovered a large population of massive submm galaxies (SMGs) at z>~1. Although it is generally believed that these galaxies host intense star-formation activity, there is growing evidence that a ...
