  • An 850-micron SCUBA map of the Groth Strip and reliable source extraction 

    Coppin, Kristen; Halpern, Mark; Scott, Douglas; Borys, Colin; Chapman, Scott (2005-03)
    We present an 850-micron map and list of candidate sources in a 70 arcmin^2 sub-area of the Groth Strip observed using SCUBA. We initially detect 7 candidate sources with signal-to-noise ratios (SNRs) between 3.0 and 3.5 ...

  • First detections of FIRBACK sources with SCUBA 

    Scott, Douglas; Lagache, Guilaine; Borys, Colin; Chapman, Scott C.; Halpern, Mark; Sajina, Anna; Ciliegi, Paolo; Clements, David L.; Dole, Herve; Oliver, Sebastian; Puget, Jean-Loup; Reach, William T.; Rowan-Robinson, Michael (1999-10-22)
    The FIRBACK (Far InfraRed BACKground) survey represents the deepest extensive 170 micron images obtained by the ISO satellite. The sources detected comprise about 10% of the Cosmic IR Background (CIB) seen by COBE, and, ...

  • A joint analysis of BLAST 250--500um and LABOCA 870um observations in the Extended Chandra Deep Field South 

    Chapin, Edward L.; Chapman, Scott C.; Coppin, Kristen E.; Devlin, Mark J.; Dunlop, James S.; Greve, Thomas R.; Halpern, Mark; Hasselfield, Matthew F.; Hughes, David H.; Ivison, Rob J.; Marsden, Gaelen; Moncelsi, Lorenzo; Netterfield, Calvin B.; Pascale, Enzo; Scott, Douglas; Smail, Ian; Viero, Marco; Walter, Fabian; Weiss, Axel; van der Werf, Paul (2011-02-11)
    We present a joint analysis of the overlapping BLAST 250, 350, 500um, and LABOCA 870um observations (from the LESS survey) of the ECDF-S. Out to z~3, the BLAST filters sample near the peak wavelength of far-infrared (FIR) ...

  • Measurement of the Sunyaev-Zel'dovich Increment in Massive Galaxy Clusters 

    Zemcov, Michael; Halpern, Mark; Borys, Colin; Chapman, Scott; Holland, Wayne; Pierpaoli, Elena; Scott, Douglas (2003-12)
    We have detected the Sunyaev-Zel'dovich (SZ) increment at 850 microns in two galaxy clusters (Cl 0016+16 and MS 1054.4-0321) using SCUBA (Sub-millimetre Common User Bolometer Array) on the James Clerk Maxwell Telescope. ...

  • The SCUBA HAlf Degree Extragalactic Survey (SHADES) - IV: Radio-mm-FIR photometric redshifts 

    Aretxaga, Itziar; Hughes, David H.; Coppin, Kristen; Mortier, Angela M. J.; Wagg, Jeff; Dunlop, James S.; Chapin, Edward L.; Eales, Stephen A.; Gaztanaga, Enrique; Halpern, Mark; Ivison, Rob J.; van Kampen, Eelco; Scott, Douglas; Serjeant, Stephen; Smail, Ian; Babbedge, Thomas; Benson, Andrew J.; Chapman, Scott; Clements, David L.; Dunne, Loretta; Dye, Simon; Farrah, Duncan; Jarvis, Matthew J.; Mann, Robert G.; Pope, Alexandra; Priddey, Robert; Rawlings, Steve; Seigar, Marc; Silva, Laura; Simpson, Chris; Vaccari, Mattia (2007-08-21)
    We present the redshift distribution of the SHADES galaxy population based on the rest-frame radio-mm-FIR colours of 120 robustly detected 850um sources in the Lockman Hole East (LH) and Subaru XMM-Newton Deep Field (SXDF). ...

  • The SCUBA HAlf Degree Extragalactic Survey (SHADES) -- VI. 350 micron mapping of submillimetre galaxies 

    Coppin, Kristen; Halpern, Mark; Scott, Douglas; Borys, Colin; Dunlop, James; Dunne, Loretta; Ivison, Rob; Wagg, Jeff; Aretxaga, Itziar; Battistelli, Elia; Benson, Andrew; Blain, Andrew; Chapman, Scott; Clements, Dave; Dye, Simon; Farrah, Duncan; Hughes, David; Jenness, Tim; van Kampen, Eelco; Lacey, Cedric; Mortier, Angela; Pope, Alexandra; Priddey, Robert; Serjeant, Stephen; Smail, Ian; Stevens, Jason; Vaccari, Mattia (2008-03)
    A follow-up survey using the Submillimetre High-Angular Resolution Camera (SHARC-II) at 350 microns has been carried out to map the regions around several 850 micron-selected sources from the Submillimetre HAlf Degree ...

  • A SCUBA Scanmap of the Hubble Deep Field: Measuring the bright end of the sub-mm source counts 

    Borys, Colin; Chapman, Scott; Halpern, Mark; Scott, Douglas (2002-03)
    Using the 850 micron SCUBA camera on the JCMT and a scanning technique different from other sub-mm surveys, we have obtained a 125 square arcminute map centered on the Hubble Deep Field. The one-sigma sensitivity to point ...

  • A search for the submillimetre counterparts to Lyman break galaxies 

    Chapman, Scott C.; Scott, Douglas; Steidel, Charles C.; Borys, Colin; Halpern, Mark; Morris, Simon L.; Adelberger, Kurt L.; Dickinson, Mark; Giavalisco, Mauro; Pettini, Max (2002-04-04)
    We have carried out targetted sub-mm observations as part of a programme to explore the connection between the rest-frame UV and far-IR properties of star-forming galaxies at high redshift, which is currently poorly ...

  • An upper limit to [C II] emission in a z ~= 5 galaxy 

    Marsden, Gaelen; Borys, Colin; Chapman, Scott C.; Halpern, Mark; Scott, Douglas (2005-05-01)
    Low-ionization-state far-infrared (FIR) emission lines may be useful diagnostics of star-formation activity in young galaxies, and at high redshift may be detectable from the ground. In practice, however, very little is ...
