Herschel PEP/HerMES: the redshift evolution of dust attenuation and of the total (UV+IR) star formation rate density
(EDP Sciences, 2013)
Using new homogeneous luminosity functions (LFs) in the far-ultraviolet (FUV) from VVDS and in the far-infrared (FIR) from Herschel/PEP and Herschel/HerMES, we studied the evolution of the dust attenuation with redshift. ...
Predicting the neutral hydrogen content of galaxies from optical data using machine learning
(Oxford University Press, 2018)
We develop a machine learning-based framework to predict the Hi content of galaxies using
more straightforwardly observable quantities such as optical photometry and environmental
parameters. We train the algorithm on z ...
The complex physics of dusty star-forming galaxies at high redshifts as revealed by Herschel and Spitzer
(IOP Publishing, 2013)
We combine far-infrared photometry from Herschel (PEP/HerMES) with deep mid-infrared spectroscopy from
Spitzer to investigate the nature and the mass assembly history of a sample of 31 luminous and ultraluminous
infrared ...
Hermes: Cosmic infrared background anisotropies and the clustering of dusty star-forming galaxies
(American Astronomical Society, 2013)
Star formation is well traced by dust, which absorbs the
UV/optical light produced by young stars in actively starforming
regions and re-emits the energy in the far-infrared/
submillimeter (FIR/submm; e.g., Savage & ...
nIFTy galaxy cluster simulations – V. Investigation of the cluster infall region
(Oxford University Press, 2016)
We examine the properties of the galaxies and dark matter haloes residing in the cluster
infall region surrounding the simulated cold dark matter galaxy cluster studied by Elahi
et al. at z = 0. The 1.1 × 1015 h−1M ...
Improving photometric redshift estimation using GPz: size information, post processing and improved photometry
(Oxford University Press, 2017)
The next generation of large-scale imaging surveys (such as those conducted with the Large Synoptic Survey Telescope and Euclid) will require accurate photometric redshifts in order to optimally extract cosmological ...
HerMES: Candidate gravitationally lensed galaxies and lensing statistics at submillimeter wavelengths
(American Astronomical Society, 2013)
Gravitational lensing increases the angular size and integrated flux of affected sources. It is exploited to investigate the mass distribution of the foreground lensing structures and the properties of the background lensed ...
MUFASA: The strength and evolution of galaxy conformity in various tracers
(Oxford University Press, 2017)
We investigate galaxy conformity using the Mufasa cosmological hydrodynamical
simulation. We show a bimodal distribution in galaxy colour with radius, albeit
with too many low-mass quenched satellite galaxies compared ...
Aligned metal absorbers and the ultraviolet background at the end of reionization
(Oxford University Press, 2018)
We use observations of spatially-aligned C ii, C iv, Si ii, Si iv, and O i absorbers to probe the
slope and intensity of the ultraviolet background (UVB) at z ∼ 6. We accom- plish this by comparing
observations with ...
Calibrating the James Webb Space telescope filters as star formation rate indicators
(American Astronomical Society, 2018)
We have calibrated the 6.5m James Webb Space Telescope (JWST) mid-infrared (MIR) filters as star formation rate
(SFR) indicators, using JWST photometry synthesized from Spitzer spectra of 49 low-redshift galaxies, which ...
