  • The Chandra Deep Protocluster Survey: Point-Source Catalogs for a 400 ks Observation of the z = 3.09 Protocluster in SSA22 

    Lehmer, B. D.; Alexander, D. M.; Chapman, S. C.; Smail, Ian; Bauer, F. E.; Brandt, W. N.; Geach, J. E.; Matsuda, Y.; Mullaney, J. R.; Swinbank, A. M. (2009-07-24)
    We present X-ray point-source catalogs for a deep 400 ks Chandra ACIS-I exposure of the SSA22 field. The observations are centred on a z = 3.09 protocluster, which is populated by Lyman break galaxies (LBGs), Lyalpha ...

  • A LABOCA survey of the Extended Chandra Deep Field South - submillimeter properties of near-IR selected galaxies 

    Greve, T. R.; Weiss, A.; Walter, F.; Smail, I.; Zheng, X. Z.; Knudsen, K. K.; Coppin, K. E. K.; Kovacs, A.; Bell, E. F.; de Breuck, C.; Dannerbauer, H.; Dickinson, M.; Gawiser, E.; Lutz, D.; Rix, H. -W; Schinnerer, E.; Alexander, D.; Bertoldi, F.; Brandt, W. N.; Chapman, S. C.; Ivison, R. J.; Koekemoer, A. M.; Kreysa, E.; Kurczynski, P.; Menten, K.; Siringo, G.; Swinbank, M.; van der Werf, P. (2009-03-31)
    Using the 330hr ESO-MPG 870-micron survey of the Extended Chandra Deep Field South (ECDF-S) obtained with the Large Apex BOlometer CAmera (LABOCA) on the Atacama Pathfinder EXperiment (APEX), we have carried out a stacking ...

  • The LABOCA survey of the Extended Chandra Deep Field South: A photometric redshift survey of submillimetre galaxies 

    Wardlow, J. L.; Smail, Ian; Coppin, K. E. K.; Alexander, D. M.; Brandt, W. N.; Danielson, A. L. R.; Luo, B.; Swinbank, A. M.; Walter, F.; Weiss, A.; Xue, Y. Q.; Zibetti, S.; Bertoldi, F.; Biggs, A. D.; Chapman, S. C.; Dannerbauer, H.; Dunlop, J. S.; Gawiser, E.; Ivison, R. J.; Knudsen, K. K.; Kovacs, A.; Lacey, C. G.; Menten, K. M.; Padilla, N.; Rix, H. -W; van der Werf, P. P. (2010-06-10)
    [abridged] We derive photometric redshifts from 17-band optical to mid-IR photometry of 74 robust counterparts to 68 of the 126 submillimetre galaxies (SMGs) selected at 870um by LABOCA observations in the ECDFS. The median ...

  • The LABOCA survey of the Extended Chandra Deep Field South: Two modes of star formation in AGN hosts? 

    Lutz, D.; Mainieri, V.; Rafferty, D.; Shao, L.; Hasinger, G.; Weiss, A.; Walter, F.; Smail, I.; Alexander, D. M.; Brandt, W. N.; Chapman, S.; Coppin, K.; Schreiber, N. M. Forster; Gawiser, E.; Genzel, R.; Greve, T. R.; Ivison, R. J.; Koekemoer, A. M.; Kurczynski, P.; Menten, K. M.; Nordon, R.; Popesso, P.; Schinnerer, E.; Silverman, J. D.; Wardlow, J.; Xue, Y. Q. (2010-01-30)
    We study the co-existence of star formation and AGN activity in X-ray selected AGN by analyzing stacked 870um submm emission from a deep and wide map of the Extended Chandra Deep Field South, obtained with LABOCA at the ...

    We present CO(2-1) observations of the submillimetre galaxy ALESS65.1 performed with the Australia Telescope Compact Array at 42.3 GHz. A previous ALMA study of submillimetre galaxies in the Extended Chandra Deep Field ...

  • 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 ...

  • The X-ray Spectral Properties of SCUBA Galaxies

    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 ...
