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 ...
H I intensity mapping with MeerKAT: Power spectrum detection in cross-correlation with WiggleZ galaxies
(Oxford University Press, 2023)
We present a detection of correlated clustering between MeerKAT radio intensity maps and galaxies from the WiggleZ Dark Energy Survey. We find a 7.7σ detection of the cross-correlation power spectrum, the amplitude of which ...
