Galaxy correlations and the BAO in a void universe: structure formation as a test of the Copernican Principle
(IOP Science, 2013)
A suggested solution to the dark energy problem is the void model, where accelerated expansion is
replaced by Hubble-scale inhomogeneity. In these models, density perturbations grow on a radially
inhomogeneous background. ...
A null test to probe the scale dependence of the growth of structure as a test of general relativity
(Oxford University Press, 2019)
The main science driver for the coming generation of cosmological surveys is understanding dark energy that relies on testing general relativity on the largest scales. Once we move beyond the simplest explanation for 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 ...
Wide-angle effects in multi-tracer power spectra with Doppler corrections
(IOP Publishing, 2023)
. We examine the computation of wide-angle corrections to the galaxy power spectrum including redshift-space distortions and relativistic Doppler corrections, and also including multiple tracers with differing clustering, ...
