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 ...
Cosmology on the largest scales with the SKA
(Proceedings of Science, 2014)
The study of the Universe on ultra-large scales is one of the major science cases for the Square
Kilometre Array (SKA). The SKA will be able to probe a vast volume of the cosmos, thus representing
a unique instrument, ...
Cosmology from HI galaxy surveys with the SKA
(Proceedings of Science, 2014)
The Square Kilometer Array (SKA) has the potential to produce galaxy redshift surveys which
will be competitive with other state of the art cosmological experiments in the next decade. In this
chapter we summarise what ...
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 ...
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 ...
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 ...
Clustering of HI galaxies in the HI parkes all sky survey and arecibo legacy fast alfa survey
(Oxford University Press, 2011)
We investigate the clustering of H I-selected galaxies in the Arecibo Legacy Fast ALFA
Survey (ALFALFA) and compare results with those obtained for the H I Parkes All Sky
Survey (HIPASS). Measurements of the angular ...
Disentangling non-gaussianity, bias, and general relativistic effects in the galaxy distribution
(American Physical Society, 2012)
Local non-Gaussianity, parametrized by
f
NL
, introduces a scale-dependent bias that is strongest at large scales, precisely where general relativistic (GR) effects also become significant. With future data, it should ...
