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 ...
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 ...
Galaxy and mass assembly: evolution of the Hα luminosity function and star formation rate density up to z < 0.35
(OUP, 2013)
Measurements of the low-z Hα luminosity function, Φ, have a large dispersion in the local number density of sources (∼0.5–1 Mpc−3 dex−1), and correspondingly in the star formation rate density (SFRD). The possible causes ...
Evolution of faint radio sources in the VIDEO-XMM3 field
(OUP, 2013)
It has been speculated that low luminosity radio-loud AGN have the potential to serve
as an important source of AGN feedback, and may be responsible for suppressing
star-formation activity in massive elliptical galaxies ...
Galaxy And Mass Assembly (GAMA): Resolving the role of environment in galaxy evolution
(Oxford University Press, 2013)
We present observations of 18 galaxies from the Galaxy And Mass Assembly (GAMA)
survey made with the SPIRAL optical integral field unit (IFU) on the Anglo- Australian Telescope. The galaxies are selected to ...
Galaxy And Mass Assembly (GAMA): spectroscopic analysis
(Oxford University Press, 2013)
The Galaxy And Mass Assembly (GAMA) survey is a multiwavelength photometric and spectroscopic
survey, using the AAOmega spectrograph on the Anglo-Australian Telescope to obtain
spectra for up to _ 300 000 galaxies over ...
Evolution of star formation in the UKIDSS ultra deep survey field - I. Luminosity functions and cosmic star formation rate out of z = 1.6
(OUP, 2013)
We present new results on the cosmic star formation history in the SXDS-UDS field out to
z = 1.6. We compile narrow-band data from the Subaru Telescope and the Visible and Infrared
Survey Telescope for Astronomy (VISTA) ...
Properties of submillimeter galaxies in the CANDELS GOODS-south field
(American Physical Society, 2014)
We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted ...
Mufasa: The assembly of the red sequence
(Oxford University Press, 2017)
We examine the growth and evolution of quenched galaxies in the Mufasa cosmo-
logical hydrodynamic simulations that include an evolving halo mass-based quench-
ing prescription, with galaxy colours computed accounting ...
