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 ...
Energetic galaxy-wide outflows in high-redshift ultra-luminous infrared galaxies hosting AGN activity
(2012-05-08)
We present integral field spectroscopy observations, covering the [O III]4959,5007 emission-line doublet of eight high-redshift (z=1.4-3.4) ultra-luminous infrared galaxies (ULIRGs) that host Active Galactic Nuclei (AGN) ...
Using [CI] to probe the Interstellar Medium in z~2.5 Sub-Millimeter Galaxies
(2013-07-24)
We present new [CI](1-0) and 12CO(4-3) Plateau de Bure Interferometer observations of five Sub-Millimeter Galaxies (SMGs) and combine these with all available [CI](1-0) literature detections in SMGs to probe the gas ...
Molecular Gas in Submillimetre-Faint, Star-Forming Ultraluminous Galaxies at z>1
(2009-10-30)
[abridged] We present interferometric CO observations of twelve z~2 submillimetre-faint, star-forming radio galaxies (SFRGs) which are thought to be ultraluminous infrared galaxies (ULIRGs) possibly dominated by warmer ...
Spectroscopic Characterisation of 250um-Selected Hyper-Luminous Star Forming Galaxies
(2010-09-28)
We present near-infrared spectroscopic observations from VLT ISAAC of thirteen 250\mu m-luminous galaxies in the CDF-S, seven of which have confirmed redshifts which average to = 2.0 \pm 0.4. Another two sources of the 13 ...
Physical Conditions of the Gas in an ALMA [CII]-identified Submillimetre Galaxy at z = 4.44
(2013-02-13)
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
(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 LABOCA Survey of the Extended Chandra Deep Field South: Clustering of submillimetre galaxies
(2011-12-01)
We present a measurement of the spatial clustering of submillimetre galaxies (SMGs) at z = 1-3. Using data from the 870 micron LESS survey, we employ a novel technique to measure the cross-correlation between SMGs and ...
Submillimeter Galaxies at z 2: Evidence for Major Mergers & Constraints on Lifetimes, IMF and CO-H2 Conversion Factor
(2008-06-10)
We report sub-arcsecond resolution IRAM PdBI millimeter CO interferometry of four z~2 submillimeter galaxies (SMGs), and sensitive CO (3-2) flux limits toward three z 2 UV-/optically selected star forming galaxies. The new ...
