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 ...
Dark energy homogeneity in general relativity: Are we applying it correctly?
(Springer, 2016)
Thus far, there does not appear to be an agreed (or adequate) definition of
homogeneous dark energy (DE). This paper seeks to define a valid, adequate homogeneity
condition for DE. Firstly, it is shown that as long as ...
Reconstruction of dark energy and expansion dynamics using Gaussian processes
(IOP Publishing, 2012)
An important issue in cosmology is reconstructing the effective dark energy equation
of state directly from observations. With few physically motivated models, future dark
energy studies cannot only be based on constraining ...
