The SCUBA-2 Large eXtragalactic Survey: 850 m map, catalogue and the bright-end number counts of the XMM-LSS field
(2023-04-30)
We present 850um imaging of the XMM-LSS field observed for 170 hours as part of the James Clerk Maxwell Telescope SCUBA-2 Large eXtragalactic Survey (S2LXS). S2LXS XMM-LSS maps an area of 9 square degrees, reaching a ...
An orientation bias in observations of submillimetre galaxies
(2022-07-28)
Recent high-resolution interferometric images of submillimetre galaxies (SMGs) reveal fascinatingly complex morphologies. This raises a number of questions: how does the relative orientation of a galaxy affect its observed ...
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 ...
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 ...
An ALMA survey of the SCUBA-2 Cosmology Legacy SurveyUKIDSS/UDS Field : Halo Masses for Submillimetre Galaxies
(2021-03-10)
We present an analysis of the spatial clustering of a large sample of high-resolution, interferometically identified, submillimetre galaxies (SMGs). We measure the projected cross-correlation function of ~350 SMGs in the ...
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 ...
The evolving far-IR galaxy luminosity function and dust-obscured star-formation rate density out to z~5
(2017-11-11)
We present a new measurement of the evolving galaxy far-IR luminosity function (LF) extending out to redshifts z~5, with resulting implications for the level of dust-obscured star-formation density in the young Universe. ...
Evolution of cosmic star formation in the SCUBA-2 Cosmology Legacy Survey
(2017-05-21)
We present a new exploration of the cosmic star-formation history and dust obscuration in massive galaxies at redshifts $0.5z 10^{10}M_\odot$ galaxies at $0.5z 10$. One third of this is accounted for by 450$\mu$m-detected ...
The SCUBA-2 Cosmology Legacy Survey: Multi-wavelength Properties of ALMA-identified Submillimeter Galaxies in UKIDSS-UDS
(2017-04-13)
We present a multi-wavelength analysis of 52 sub-millimeter galaxies (SMGs), identified using ALMA 870$\mu$m continuum imaging in a pilot program to precisely locate bright SCUBA2-selected sub-mm sources in the UKIDSS Ultra ...
