Null tests of the cosmological constant using supernovae
(American Physical Society, 2014)
The standard concordance model of the Universe is based on the cosmological constant as the
driver of accelerating expansion. This concordance model is being subjected to a growing range
of inter-locking observations. ...
The star-formation history of mass-selected galaxies from the VIDEO survey
(Oxford University Press, 2014)
We measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data. We split the sample, which spans 0 ...
Properties of submillimeter galaxies in the CANDELS GOODS-south field
(American Physical Society, 2014)
We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted ...
Optical-faint, far-infrared-bright Herschel sources in the CANDELS fields: Ultra-luminous infrared galaxies at z > 1 and the effect of source blending
(American Astronomical Society, 2014)
The Herschel very wide-field surveys have charted hundreds of square degrees in multiple far-IR
(FIR) bands. While the Sloan Digital Sky Survey (SDSS) is currently the best resource for optical
counterpart identifications ...
Testing foundations of modern cosmology with SKA all-sky surveys
(Proceedings of Science, 2014)
Continuum and HI surveys with the Square Kilometre Array (SKA) will allow us to probe some of
the most fundamental assumptions of modern cosmology, including the Cosmological Principle.
SKA all-sky surveys will map an ...
Measuring redshift-space distortion with future SKA surveys
(Proceedings of Science, 2014)
The peculiar motion of galaxies can be a particularly sensitive probe of gravitational collapse. As
such, it can be used to measure the dynamics of dark matter and dark energy as well the nature
of the gravitational laws ...
Model-independent constraints on dark energy and modified gravity with the SKA
(Proceedings of Science, 2014)
Employing a nonparametric approach of the principal component analysis (PCA), we forecast
the future constraint on the equation of state w(z) of dark energy, and on the effective Newton
constant m(k; z), which parameterise ...
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 ...
