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 ...
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 ...
