The star-formation history of mass-selected galaxies from the VIDEO survey
(Oxford University Press, 2014)
We measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data. We split the sample, which spans 0 ...
SKAO HI intensity mapping: blind foreground subtraction challenge
(University of the Western Cape, 2022)
Neutral Hydrogen Intensity Mapping (H I IM) surveys will be a powerful new probe of cosmology. However, strong astrophysical
foregrounds contaminate the signal and their coupling with instrumental systematics further ...
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 ...
A deep search for faint galaxies associated with very low-redshift C iv absorbers: A case with cold-accretion characteristics
(The American Astronomical Society, 2013)
Studies of QSO absorber–galaxy connections are often hindered by inadequate information on whether faint/dwarf
galaxies are located near the QSO sight lines. To investigate the contribution of faint galaxies to QSO ...
Isothermal dust models of Herschel-ATLAS galaxies
(Oxford University Press, 2013)
We use galaxies from the Herschel-ATLAS survey, and a suite of ancillary simulations based on an isothermal dust model, to study our ability to determine the effective dust temperature, luminosity and emissivity index of ...
Calibrating photometric redshifts with intensity mapping observations
(American Physical Society, 2017)
Imaging surveys of galaxies will have a high number density and angular resolution yet a poor
redshift precision. Intensity maps of neutral hydrogen (HI) will have accurate redshift resolution
yet will not resolve ...
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 ...
Optical-faint, far-infrared-bright Herschel sources in the CANDELS fields: Ultra-luminous infrared galaxies at z > 1 and the effect of source blending
(American Astronomical Society, 2014)
The Herschel very wide-field surveys have charted hundreds of square degrees in multiple far-IR
(FIR) bands. While the Sloan Digital Sky Survey (SDSS) is currently the best resource for optical
counterpart identifications ...
Black hole - galaxy correlations without self-regulation
(American Astronomical Society, 2013)
Recent models of black hole growth in a cosmological context have forwarded a paradigm in which the growth
is self-regulated by feedback from the black hole itself. Here we use cosmological zoom simulations of galaxy
formation ...
Einstein's legacy in galaxy surveys
(Oxford University Press, 2015)
Non-Gaussianity in the primordial fluctuations that seeded structure formation produces a signal in the galaxy power spectrum on very large scales. This signal contains vital information about the primordial Universe, but ...
