Violent quenching : Molecular Gas Blown to 1000 km s -1 during a Major Merger
(2018-08-23)
We present Atacama Large Millimeter/submillimeter Array observations of a massive () compact ( pc) merger remnant at z = 0.66 that is driving a 1000 km s -1 outflow of cool gas, with no observational trace of an active ...
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 ...
Cluster richness-mass calibration with cosmic microwave background lensing
(2017-11-01)
Identifying galaxy clusters through overdensities of galaxies in photometric surveys is the oldest and arguably the most economic and mass-sensitive detection method, compared to X-ray and Sunyaev-Zel'dovich Effect surveys ...
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′ ...
ALMA observations of a z ≈ 3.1 protocluster : Star formation from active galactic nuclei and Lyman-alpha blobs in an overdense environment
(2016-09-21)
We exploit Atacama Large Interferometer Array (ALMA) 870 μm observations to measure the star formation rates (SFRs) of eight X-ray detected active galactic nuclei (AGNs) in a z ≈ 3.1 protocluster, four of which reside in ...
Herschel protocluster survey : A search for dusty star-forming galaxies in protoclusters at z = 2-3
(2016-08-21)
We present a Herschel/Spectral and Photometric Imaging Receiver (SPIRE) survey of three protoclusters at z = 2-3 (2QZCluster, HS1700, SSA22). Based on the SPIRE colours (S350/S250 and S500/S350) of 250 μm sources, we ...
