# Model selection forecasts for the spectral index from the Planck satellite

@article{Pahud2006ModelSF, title={Model selection forecasts for the spectral index from the Planck satellite}, author={C'edric Pahud and Andrew R. Liddle and Pia Mukherjee and David Parkinson}, journal={Physical Review D}, year={2006}, volume={73}, pages={123524} }

The 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 favour) the…

We use Bayesian model selection tools to forecast the Planck satellite's ability to distinguish between different models for the re-ionization history of the Universe, using the large angular scale…

Model selection in cosmology

- Physics
- 2006

The CosmoNest code is described, the first computationally efficient implementation of Bayesian model selection in a cosmological context, and it is applied to recent WMAP satellite data, examining the need for a perturbation spectral index differing from the scale-invariant (Harrison-Zel'dovich) case.

Bayesian model selection analysis of WMAP3

- Computer Science
- 2006

While the Bayesian evidence supports the conclusion that nS 6= 1, the data are not yet powerful enough to do so at a strong or decisive level, and inclusion of r as a parameter weakens the conclusion against the Harrison–Zel’dovich case.

This work discusses possible alternate models that give better fits on large scales and applies a model-comparison technique to select amongst them and finds that models with a cutoff in the power spectrum at large scales are indeed preferred by data, but only by a factor of 3.6.
