An ALMA Survey of Submillimeter Galaxies in the Extended Chandra Deep Field South: The AGN Fraction and X-ray Properties of Submillimeter Galaxies
S. X. Wang, W. N. Brandt, B. Luo +17
The large gas and dust reservoirs of submm galaxies (SMGs) could potentially provide ample fuel to trigger an Active Galactic Nucleus (AGN), but previous studies of the AGN fractio…
An ALMA Survey of Submillimeter Galaxies in the Extended Chandra Deep Field South: The Redshift Distribution and Evolution of Submillimeter Galaxies
James Simpson, Mark Swinbank, Ian Smail +21
We present the first photometric redshift distribution for a large unbiased sample of 870um selected submillimeter galaxies (SMGs) with robust identifications based on observations…
13CO and C18O emission from a dense gas disk at z=2.3: abundance variations, cosmic rays and the initial conditions for star formation
A. L. R. Danielson, A. M. Swinbank, Ian Smail +6
We analyse the SLEDs of 13CO and C18O for the J=1-0 up to J=7-6 transitions in the gravitationally lensed ultraluminous infrared galaxy SMMJ2135-0102 at z=2.3. This is the first de…
The SCUBA-2 Cosmology Legacy Survey: demographics of the 450 μm-population
I. G. Roseboom, J. S. Dunlop, M. Cirasuolo +47
We investigate the multi-wavelength properties of a sample of 450-μm selected sources from the SCUBA-2 Cosmology Legacy Survey (S2CLS). A total of 69 sources were identified above…
Using [CI] to probe the Interstellar Medium in z~2.5 Sub-Millimeter Galaxies
S. Alaghband-Zadeh, S. C. Chapman, A. M. Swinbank +7
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…
An ALMA survey of submillimeter galaxies in the Extended Chandra Deep Field South: Source catalog and multiplicity
J. A. Hodge, A. Karim, I. Smail +24
We present an Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 0 survey of 126 submillimeter sources from the LABOCA ECDFS Submillimeter Survey (LESS). Our 870 micron surv…
The SCUBA-2 Cosmology Legacy Survey: blank-field number counts of 450um-selected galaxies and their contribution to the cosmic infrared background
J. E. Geach, E. L. Chapin, K. E. K. Coppin +50
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 ma…
An ALMA survey of submillimetre galaxies in the Extended Chandra Deep Field South: High resolution 870um source counts
Alexander Karim, Mark Swinbank, Jackie Hodge +20
We report the first counts of faint submillimetre galaxies (SMG) in the 870-um band derived from arcsecond resolution observations with the Atacama Large Millimeter Array (ALMA). W…
An ALMA survey of Sub-millimetre Galaxies in the Extended Chandra Deep Field South: Detection of [C II] at z=4.4
Mark Swinbank, Alexander Karim, Ian Smail +19
We present ALMA 870-um (345GHz) observations of two sub-millimetre galaxies (SMGs) drawn from an ALMA study of the 126 sub-millimeter sources from the LABOCA Extended Chandra Deep…
The evolutionary connection between QSOs and SMGs: molecular gas in far-infrared luminous QSOs at z ~ 2.5
J. M. Simpson, Ian Smail, A. M. Swinbank +23
We present IRAM Plateau de Bure Interferometer observations of the 12CO(3-2) emission from two far-infrared luminous QSOs at z ~ 2.5 selected from the Herschel-ATLAS survey. These…
A Herschel view of the far-infrared properties of submillimetre galaxies
B. Magnelli, D. Lutz, P. Santini +48
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 Evolutio…
The Cosmic History of Hot Gas Cooling and Radio AGN Activity in Massive Early-Type Galaxies
A. L. R. Danielson, B. D. Lehmer, D. M. Alexander +5
We study the X-ray properties of 393 optically selected early-type galaxies (ETGs) over the redshift range of z~0.0-1.2 in the Chandra Deep Fields. To measure the average X-ray pro…
The LABOCA survey of the Extended Chandra Deep Field South: A photometric redshift survey of submillimetre galaxies
J. L. Wardlow, Ian Smail, K. E. K. Coppin +23
[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 L…
