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

    Coppin, Kristen, Mark Halpern, Douglas Scott, Colin Borys, et al. 2005. "An 850-micron SCUBA map of the Groth Strip and reliable source extraction." Monthly Notices of the Royal Astronomical Society 357(3): 1022-1028
    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, Guilaine Lagache, Colin Borys, Scott C. Chapman, et al. 1999. "First detections of FIRBACK sources with SCUBA." Astronomy and Astrophysics 357:L5
    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., Scott C. Chapman, Kristen E. Coppin, Mark J. Devlin, et al. 2011. "A joint analysis of BLAST 250--500um and LABOCA 870um observations in the Extended Chandra Deep Field South." 411(1): 505-549
    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, Mark Halpern, Colin Borys, Scott Chapman, et al. 2003. "Measurement of the Sunyaev-Zel'dovich Increment in Massive Galaxy Clusters." Monthly Notices of the Royal Astronomical Society 346(4): 1179-1188
    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, David H. Hughes, Kristen Coppin, Angela M. J. Mortier, et al. 2007. "The SCUBA HAlf Degree Extragalactic Survey (SHADES) - IV: Radio-mm-FIR photometric redshifts." Monthly Notices of the Royal Astronomical Society 379(4): 1571-1588
    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, Mark Halpern, Douglas Scott, Colin Borys, et al. 2008. "The SCUBA HAlf Degree Extragalactic Survey (SHADES) -- VI. 350 micron mapping of submillimetre galaxies." Monthly Notices of the Royal Astronomical Society 384(4):1597-1610
    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, Scott Chapman, Mark Halpern, and Douglas Scott. 2002. "A SCUBA Scanmap of the HDF: Measuring the bright end of the sub-mm source counts." Monthly Notices of the Royal Astronomical Society 330(3): 63-L67
    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., Douglas Scott, Charles C. Steidel, Colin Borys, et al. 2002. "A search for the submillimetre counterparts to Lyman break galaxies." Monthly Notices of the Royal Astronomical Society 319(1): 318-330
    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, Colin Borys, Scott C. Chapman, Mark Halpern, et al. 2005. "An upper limit to [C II] emission in a z ~= 5 galaxy." Monthly Notices of the Royal Astronomical Society 359(1): 43-46
    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 ...
