Improvements in cosmological constraints from breaking growth degeneracy
Perenon, Louis; Ilic, St´ephane; Maartens, Roy (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 ...
