The host haloes of O I absorbers in the reionization epoch
(Oxford University Press, 2013)
We use a radiation hydrodynamic simulation of the hydrogen reionization epoch to study
OI absorbers at z ∼ 6. The intergalactic medium (IGM) is reionized before it is enriched;
hence, OI absorption originates within dark ...
Stacked reverberation mapping
(Oxford University Press, 2013)
Over the past 20 years reverberation mapping has proved one of the most successful techniques
for studying the local (<1 pc) environment of supermassive black holes that drive active
galactic nuclei. Key successes of ...
Physical properties of spectroscopically confirmed galaxies at Z ≥ 6. I. Basic characteristics of the rest-frame UV continuum and lyman-alpha emission
(American Astronomical Society, 2013)
We present deep HST near-IR and Spitzer mid-IR observations of a large sample of spectroscopically-
confirmed galaxies at z ≥ 6. The sample consists of 51 Ly-alpha emitters (LAEs) at z ≃ 5.7, 6.5, and 7.0,
and 16 Lyman-break ...
The roles of star formation and AGN activity of IRS sources in the HerMES fields
(Oxford University Press, 2013)
In this work we explore the impact of the presence of an active galactic nucleus (AGN)
on the mid- and far-infrared (IR) properties of galaxies as well as the effects of simultaneous
AGN and starburst activity in these ...
Hunting down horizon-scale effects with multi-wavelength surveys
(American Astronomical Society, 2015)
Next-generation cosmological surveys will probe ever larger volumes of the universe, including the largest scales, near and beyond the horizon. On these scales, the galaxy power spectrum carries signatures of local primordial ...
Radio continuum surveys with square kilometre array pathfinders
(Cambridge University Press, 2013)
In the lead-up to the Square Kilometre Array (SKA) project, several next-generation
radio telescopes and upgrades are already being built around the world. These include APERTIF
(The Netherlands), ASKAP (Australia), ...
Revealing the cold dust in low-metallicity environments: I. Photometry analysis of the Dwarf Galaxy Survey with Herschel
(EDP Sciences, 2013)
Context. We present new photometric data from our Herschel Guaranteed Time Key Programme, the Dwarf
Galaxy Survey (DGS),
dedicated to the observation of the gas and dust in low-metallicity environments. A total of 48 ...
HELP: The Herschel Extragalactic Legacy Project
(Oxford University Press, 2021)
We present the Herschel Extragalactic Legacy Project (HELP). This project collates, curates, homogenizes and creates derived data products for most of the premium multiwavelength extragalactic data sets. The sky boundaries ...
Statistical recovery of the BAO scale from multipoles of the beam-convolved 21 cm correlation function
(Royal Astronomical Society, 2021)
Despite being designed as an interferometer, theMeerKAT radio array (a Square Kilometre Array pathfinder) can also be used in
autocorrelation (‘single-dish’) mode, where each dish scans the sky independently. Operating ...
A deep radio view of the evolution of the cosmic star formation rate density from a stellar-mass-selected sample in VLA-COSMOS
(Royal Astronomical Society, 2022)
We present the 1.4 GHz radio luminosity functions (RLFs) of galaxies in the Cosmic Evolution Survey (COSMOS) field, measured above and below the 5σ detection threshold, using a Bayesian model-fitting technique. The radio ...
