Cosmic evolution of the H2 mass density and the epoch of molecular gas
(2021-05-05)
We present new empirical constraints on the evolution of ρ H2, the cosmological mass density of molecular hydrogen, back to z ≈ 2.5. We employ a statistical approach measuring the average observed 850 μm flux density of ...
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 ...
A Magnified View of Circumnuclear Star Formation and Feedback around an Active Galactic Nucleus at z = 2.6
(2018-10-10)
We present Atacama Large Millimeter/submillimeter Array observations of an intrinsically radio-bright (L 1.4 GHz = (1.7 ± 0.1) ×10 25 W Hz -1) and infrared luminous (L IR ≈ 10 13 L o) galaxy at z = 2.6. The infrared-to-radio ...
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 ...
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′ ...
Imaging the environment of A z = 6.3 submillimeter galaxy with scuba-2
(2014-08-28)
We describe a search for submillimeter emission in the vicinity of one of the most distant, luminous galaxies known, HerMES FLS3, at z = 6.34, exploiting it as a signpost to a potentially biased region of the early universe, ...
