Model selection forecasts for the spectral index from the Planck satellite
journal contribution
posted on 2023-06-08, 07:37 authored by Cédric Pahud, Andrew R Liddle, Pia Mukherjee, David ParkinsonThe recent WMAP3 results have placed measurements of the spectral index nS in an interesting position. While parameter estimation techniques indicate that the Harrison–Zel’dovich spectrum nS=1 is strongly excluded (in the absence of tensor perturbations), Bayesian model selection techniques reveal that the case against nS=1 is not yet conclusive. In this paper, we forecast the ability of the Planck satellite mission to use Bayesian model selection to convincingly exclude (or favor) the Harrison–Zel’dovich model.
