Constraints on $$\sigma _8$$ σ 8 and degeneracies from linear Nash-Greene perturbations in subhorizon scale
Abstract Using a joint statistical analysis, we test a four-dimensional FLRW model embedded in a five-dimensional bulk based on the Nash-Greene embedding theorem. Performing a Markov Chain Monte Carlo (MCMC) modelling, we combine observational data sets as those of the recent growth data, the best-f...
