The nature of the variable millimetre-selected AGN in the Brightest Cluster Galaxy of Abell 851
(2018-11-21)
We present the detection of a bright 3mm continuum source in the brightest cluster galaxy (BCG) in Abell 0851 (z = 0.411) with the NOrthern Extended Millimeter Array (NOEMA). When this detection is compared to other ...
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 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 ...
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 ...
