Revealing the Stellar Mass and Dust Distributions of Submillimeter Galaxies at Redshift 2
(2019-07-03)
We combine high-resolution ALMA and HST/CANDELS observations of 20 submillimeter galaxies (SMGs), predominantly from the AS2UDS survey at z ≃ 2, with bright rest-frame optical counterparts () to investigate the resolved ...
An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field : Source catalogue and properties
(2019-06-06)
We present the catalogue and basic properties of sources in AS2UDS, an 870-\mum continuum survey with the Atacama Large Millimetre/sub-millimetre Array (ALMA) of 716 single-dish sub-millimetre sources detected in the ...
AzTEC 1.1 mm observations of high-z protocluster environments : SMG overdensities and misalignment between AGN jets and SMG distribution
(2018-10)
We present observations at 1.1 mm towards 16 powerful radio galaxies and a radio-quiet quasar at 0.5 > z > 6.3 acquired with the AzTEC camera mounted at the James Clerk Maxwell Telescope and Atacama Submillimeter Telescope ...
A direct calibration of the IRX-β relation in Lyman-break Galaxies at z=3-5
(2018-10)
We use a sample of 4209 Lyman-break galaxies (LBGs) at z ≃ 3, 4, and 5 in the UKIRT Infrared Deep Sky Survey Ultra Deep Survey field to investigate the relationship between the observed slope of the stellar continuum ...
A machine-learning method for identifying multi-wavelength counterparts of submillimeter galaxies : training and testing using AS2UDS and ALESS
(2018-07-27)
We describe the application of supervised machine-learning algorithms to identify the likely multiwavelength counterparts to submillimeter sources detected in panoramic, single-dish submillimeter surveys. As a training ...
An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field : number counts of submillimeter galaxies
(2018-06-25)
We report the first results of AS2UDS, an 870 μm continuum survey with the Atacama Large Millimeter/Submillimeter Array (ALMA) of a total area of ∼50 arcmin 2 comprising a complete sample of 716 submillimeter sources drawn ...
Red, redder, reddest : SCUBA-2 imaging of colour-selected Herschel sources
(2018-06-11)
High-redshift, luminous, dusty star-forming galaxies (DSFGs) constrain the extremity of galaxy formation theories. The most extreme are discovered through follow-up on candidates in large area surveys. Here, we present ...
Dust attenuation in 2<z<3 star-forming galaxies from deep ALMA observations of the Hubble Ultra Deep Field
(2018-05-21)
We present the results of a new study of the relationship between infrared excess (IRX ≡ L IR/L UV), ultraviolet (UV) spectral slope (β) and stellar mass at redshifts 2 < z < 3, based on a deep Atacama Large Millimeter ...
The dust and [CII] morphologies of redshift ~4.5 sub-millimeter galaxies at ~200pc resolution : The Absence of Large Clumps in the Interstellar Medium at High-redshift
(2018-05-17)
We present deep, high-resolution (0.″03, 200 pc) ALMA Band 7 observations covering the dust continuum and [C ii] λ157.7 μm emission in four z ∼4.4-4.8 sub-millimeter galaxies (SMGs) selected from the ALESS and AS2UDS ...
VLA and ALMA IMAGING of INTENSE GALAXY-WIDE STAR FORMATION in z ∼ 2 GALAXIES
(2016-12-01)
We present ≃0.″4 resolution extinction-independent distributions of star formation and dust in 11 star-forming galaxies (SFGs) at z = 1.3-3.0. These galaxies are selected from sensitive blank-field surveys of the 2′ ×2′ ...
