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

    Alexander, D. M., W. N. Brandt, I. Smail, A. M. Swinbank, et al. 2008. "Weighing the Black Holes in z~2 Submillimeter-Emitting Galaxies Hosting Active Galactic Nuclei." The Astronomical Journal 135(5): 1968-1981
    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., A. Shapley, C. Steidel, and R. Windhorst. 2002. "Westphal-MMD11: An interacting, submillimeter luminous Lyman break galaxy." The Astrophysical Journal 572(1): 1-L5
    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., F. E. Bauer, S. C. Chapman, I. Smail, et al. 2005. "The X-ray Spectral Properties of SCUBA Galaxies." The Astrophysical Journal 632(2): 736-750
    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 ...
