Using sparse gaussian processes for predicting robust inertial confinement fusion implosion yields
(arXiv, 2019)
Here we present the application of an advanced
Sparse Gaussian Process based machine learning algorithm to
the challenge of predicting the yields of inertial confinement
fusion (ICF) experiments. The algorithm is used ...
Extracting the global signal from 21-cm fluctuations: the multitracer approach
(Oxford University Press, 2019)
The multitracer technique employs a ratio of densities of two differently biased galaxy samples that trace the same underlying matter density field, and was proposed to alleviate the cosmic variance problem. Here, we propose ...
Measuring the H I mass function below the detection threshold
(Oxford University Press, 2019-10-30)
We present a Bayesian stacking technique to directly measure the H I mass function (HIMF)
and its evolution with redshift using galaxies formally below the nominal detection threshold.
We generate galaxy samples over ...
Radio-loud active calactic nucleus: is there a link between luminosity and cluster environment?
(American Physical Society, 2013)
We present here the first results from the Chandra ERA (Environments of Radio-loud AGN) Large Project,
characterizing the cluster environments of a sample of 26 radio-loud active galactic nuclei (AGNs) at z ∼ 0.5
that ...
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 ...
