The ramp-up of interstellar medium enrichment at z>4
(2021-11-04)
Fluorine is one of the most interesting elements for nuclear and stellar astrophysics 1,2. Fluorine abundance was first measured for stars other than the Sun in 1992 1, then for a handful of metal-poor stars 3, which are ...
An ALMA survey of the S2CLS UDS field: optically invisible submillimetre galaxies
(2021-04-01)
We analyse a robust sample of 30 near-infrared-faint (KAB > 25.3, 5σ) submillimetre galaxies (SMGs) selected from a 0.96 deg2 field to investigate their properties and the cause of their faintness in optical/near-infrared ...
An ALMA survey of the SCUBA-2 CLS UDS field: physical properties of 707 sub-millimetre galaxies
(2020-05)
We analyse the physical properties of a large, homogeneously selected sample of ALMA-located sub-mm galaxies (SMGs) detected in the SCUBA-2 CLS 850-$\mu$m map of the UKIDSS/UDS field. This survey, AS2UDS, identified 707 ...
An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field : Dust attenuation in high-redshift Lyman break Galaxies
(2020-03)
We analyse 870um Atacama Large Millimetre Array (ALMA) dust continuum detections of 41 canonically-selected z~3 Lyman-break galaxies (LBGs), as well as 209 ALMA-undetected LBGs, in follow-up of SCUBA-2 mapping of the UKIDSS ...
Multi-wavelength properties of radio and machine-learning identified counterparts to submillimeter sources in S2COSMOS
(2019-11-20)
We identify multi-wavelength counterparts to 1,147 submillimeter sources from the S2COSMOS SCUBA-2 survey of the COSMOS field by employing a recently developed radio$+$machine-learning method trained on a large sample of ...
The SCUBA-2 Cosmology Legacy Survey : 850um maps, catalogues and number counts
(2016-11-10)
We present a catalogue of nearly 3,000 submillimetre sources detected at 850um over ~5 square degrees surveyed as part of the James Clerk Maxwell Telescope (JCMT) SCUBA-2 Cosmology Legacy Survey (S2CLS). This is the largest ...
A resolved map of the infrared excess in a Lyman Break Galaxy at z=3
(2016-09-10)
We have observed the dust continuum of ten z=3.1 Lyman Break Galaxies with the Atacama Large Millimeter/Submillimeter Array at ~450 mas resolution in Band 7. We detect and resolve the 870um emission in one of the targets ...
The average submillimetre properties of Lyman-alpha Blobs at z=3
(2016-08-21)
Ly-alpha blobs (LABs) offer insight into the complex interface between galaxies and their circumgalactic medium. Whilst some LABs have been found to contain luminous star-forming galaxies and active galactic nuclei that ...
