Sample variance, source clustering and their influence on the counts of faint radio sources
(Oxford University Press, 2013)
The shape of the curves defined by the counts of radio sources per unit area as a function of their
flux density was one of the earliest cosmological probes. Radio source counts continue to be
an area of astrophysical ...
VLT/XSHOOTER & Subaru/MOIRCS spectroscopy of HUDF-YD3: No evidence for Lyman-alpha emission at z=8.55
(Oxford University Press, 2013)
We present spectroscopic observations with VLT/XSHOOTER and Subaru/MOIRCS of a relatively bright Y -band drop-out galaxy in the Hubble Ultra Deep Field, first selected by Bunker et al. (2010), McLure et al. (2010) and ...
The faint radio source population at 15.7 GHz - II. Multi-wavelength properties
(Oxford University Press, 2015)
A complete, flux density limited sample of 96 faint (> 0:5 mJy) radio sources is selected
from the 10C survey at 15.7 GHz in the Lockman Hole. We have matched this sample to a
range of multi-wavelength catalogues, including ...
The faint source population at 15.7 GHz - I. The radio properties
(Oxford University Press, 2013)
We have studied a sample of 296 faint (>0.5 mJy) radio sources selected from an area of
the Tenth Cambridge (10C) survey at 15.7 GHz in the Lockman Hole. By matching this
catalogue to several lower frequency surveys (e.g. ...
The preferentially magnified active nucleus in IRAS F10214+4724 - III. VLBI observations of the radio core
(Oxford University Press, 2013)
We report 1.7GHz very long baseline interferometry (VLBI) observations of IRAS F10214+4724, a lensed z = 2.3 obscured quasar with prodigious star formation. We detect what we argue to be the obscured active nucleus with ...
Cosmology with a SKA HI intensity mapping survey
(Proceedings of Science, 2014)
HI intensity mapping (IM) is a novel technique capable of mapping the large-scale structure of
the Universe in three dimensions and delivering exquisite constraints on cosmology, by using HI
as a biased tracer of the ...
Overview of Cosmology with the SKA
(Proceedings of Science, 2014)
The new frontier of cosmology will be led by three-dimensional surveys of the large-scale structure of the Universe. Based on its all-sky surveys and redshift depth, the SKA is destined to revolutionize cosmology, in ...
