Improvements in cosmological constraints from breaking growth degeneracy
(EDP Sciences, 2020)
The key probes of the growth of a large-scale structure are its rate f and amplitude σ8. Redshift space distortions in the galaxy power spectrum allow us to measure only the combination fσ8, which can be used to constrain ...
The Hubble constant tension with next-generation galaxy surveys
(IOP Publishing Ltd, 2020)
The rate at which the universe is expanding today is a fundamental parameter in
cosmology which governs our understanding of structure formation and dark energy. However, current measurements of the Hubble constant, H0, ...
