Redshift-space distortions as a probe of dark energy
(University of Western Cape, 2014)We begin by finding a system of differential equations for the background and linearly perturbed variables in the standard, ɅCDM model, using the Einstein Field Equations, and then solving these numerically. Later, we ... -
Testing gravity with redshift-space distortions, using MeerKAT and the SKA
(University of the Western Cape, 2019)The growth rate of large-scale structure is a key probe of gravity in the accelerating Universe. Standard models of Dark Energy within General Relativity predict essentially the same growth rate, whereas Modified Gravity ...
