Main sequence of star forming galaxies beyond the Herschel confusion limit
(2018-07-30)
Context. Deep far-infrared (FIR) cosmological surveys are known to be affected by source confusion, causing issues when examining the main sequence (MS) of star forming galaxies. In the past this has typically been partially ...
The distribution of local star formation activity as a function of galaxy stellar mass, environment and morphology
(2017-12-21)
We present a detailed inventory of star formation in the local Universe, dissecting the cosmic star formation budget as a function of key variables that influence the star formation rate (SFR) of galaxies: stellar mass, ...
A complete distribution of redshifts for sub-millimetre galaxies in the SCUBA-2 Cosmology Legacy Survey UDS field
(2017-10-21)
Sub-milllimetre galaxies (SMGs) are some of the most luminous star-forming galaxies in the Universe, however their properties remain hard to determine due to the difficulty of identifying their optical\slash near-infrared ...
Observational evidence that positive and negative AGN feedback depends on galaxy mass and jet power
(2017-10-11)
Several studies support the existence of a link between the AGN and star formation activity. Radio jets have been argued to be an ideal mechanism for direct interaction between the AGN and the host galaxy. A drawback of ...
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 ...
Herschel-ATLAS: Revealing dust build-up and decline across gas, dust and stellar mass selected samples: I. Scaling relations
(2017-02-01)
We present a study of the dust, stars and atomic gas (HI) in an HI-selected sample of local galaxies (z 80 per cent), low stellar mass sources that appear to be in the earliest stages of their evolution. We compare this ...
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 ...
ATCA detections of massive molecular gas reservoirs in dusty, high-z radio galaxies
(2016-10-27)
Observations using the 7 mm receiver system on the Australia Telescope Compact Array have revealed large reservoirs of molecular gas in two high-redshift radio galaxies: HATLAS J090426.9+015448 (z = 2.37) and HATLAS ...
The Herschel-ATLAS Data Release 1 Paper II : Multi-wavelength counterparts to submillimetre sources
(2016-10-21)
This paper is the second in a pair of articles presenting data release 1 (DR1) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS), the largest single open-time key project carried out with the Herschel ...
LOFAR/H-ATLAS: A deep low-frequency survey of the Herschel-ATLAS North Galactic Pole field
(2016-10-21)
We present LOFAR High-Band Array (HBA) observations of the Herschel-ATLAS North Galactic Pole survey area. The survey we have carried out, consisting of four pointings covering around 142 square degrees of sky in the ...
