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 ...
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 ...
The Herschel* view of the environment of the radio galaxy 4C+41.17 at z = 3.8
(Oxford University Press, 2013)
We present Herschel observations at 70, 160, 250, 350 and 500 μm of the environment of the
radio galaxy 4C+41.17 at z = 3.792. About 65 per cent of the extracted sources are securely
identified with mid-infrared sources ...
