A robust sample of submillimetre galaxies: constraints on the prevalence of dusty, high-redshift starbursts
(2005-12-11)
The modest significance of most sources detected in current submm surveys can potentially compromise some analyses due to the inclusion of spurious sources in catalogues typically selected at >3.0-3.5sigma. Here, we develop ...
AzTEC Half Square Degree Survey of the SHADES Fields -- I. Maps, Catalogues, and Source Counts
(2009-07-06)
We present the first results from the largest deep extragalactic millimetre-wavelength survey undertaken to date. These results are derived from maps covering over 0.7 deg^2, made at 1.1mm, using the AzTEC continuum camera ...
Luminous Starbursts in the Redshift Desert at z 1-2: Star Formation Rates, Masses & Evidence for Outflows
(2011-08-01)
We present a spectroscopic catalogue of 40 luminous starburst galaxies at z=0.7--1.7 (median z=1.3). 19 of these are submillimetre galaxies (SMGs) and 21 are submillimetre-faint radio galaxies (SFRGs). This sample helps ...
A Herschel view of the far-infrared properties of submillimetre galaxies
(2012-02-03)
We study a sample of 61 submillimetre galaxies (SMGs) selected from ground-based surveys, with known spectroscopic redshifts and observed with Herschel as part of the PACS Evolutionary Probe (PEP) and the Herschel Multi-tiered ...
The SCUBA-2 Cosmology Legacy Survey: Ultraluminous star-forming galaxies in a z=1.6 cluster
(2013-12-11)
We analyse new SCUBA-2 submillimeter and archival SPIRE far-infrared imaging of a z=1.62 cluster, Cl0218.3-0510, which lies in the UKIDSS/UDS field of the SCUBA-2 Cosmology Legacy Survey. Combining these tracers of obscured ...
The SCUBA-2 Cosmology Legacy Survey: demographics of the 450 \mu m-population
(2013-08-20)
We investigate the multi-wavelength properties of a sample of 450-\mu m selected sources from the SCUBA-2 Cosmology Legacy Survey (S2CLS). A total of 69 sources were identified above 4\sigma\ in deep SCUBA-2 450-\mu m ...
The LABOCA survey of the Extended Chandra Deep Field South: A photometric redshift survey of submillimetre galaxies
(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 SCUBA-2 Cosmology Legacy Survey: blank-field number counts of 450um-selected galaxies and their contribution to the cosmic infrared background
(2012-11-28)
The first deep blank-field 450um map (1-sigma~1.3mJy) from the SCUBA-2 Cosmology Legacy Survey (S2CLS), conducted with the James Clerk Maxwell Telescope (JCMT) is presented. Our map covers 140 arcmin^2 of the COSMOS field, ...
