Constraining the growth rate by combining multiple future surveys
(IOP Publishing, 2020)
The growth rate of large-scale structure provides a powerful consistency test of
the standard cosmological model and a probe of possible deviations from general relativity.
We use a Fisher analysis to forecast constraints ...
Testing homegeneity with Galaxy Star formation histories
(IOP Publishing, 2013)
Observationally confirming spatial homogeneity on sufficiently large cosmological scales is of importance to test
one of the underpinning assumptions of cosmology, and is also imperative for correctly interpreting dark ...
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 ...
Probing the imprint of interacting dark energy on very large scales
(American Physical Society, 2015)
The observed galaxy power spectrum acquires relativistic corrections from light-cone effects, and these corrections grow on very large scales. Future galaxy surveys in optical, infrared and radio bands will probe increasingly ...
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, ...
Nonlinear modulation of the HI power spectrum on ultra-large scales. I
(IOP Science, 2015)
Intensity mapping of the neutral hydrogen brightness temperature promises to provide a three-dimensional view of the universe on very large scales. Nonlinear effects are typically thought to alter only the small-scale ...
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 ...
