Bayesian evidence for the tensor-to-scalar ratio r and neutrino masses m_nu: Effects of uniform vs logarithmic priors (supplementary inference products)

  • 1. University of Cambridge

Description

These are the nested sampling inference products and input files that were used to compute results for arXiv:2102.11511.

Example plotting scripts (as .ipynb or as .html files) and figures from the papers are included to demonstrate usage.

 

Filename conventions:

  • lcdm: Concordance cosmological model called \(\Lambda\mathrm{CDM}\) (without extension this assumes \(r=0\) and a single massive neutrino with mass \(m_\nu=0.06\,\mathrm{eV}\)).
  • _r: \(\Lambda\mathrm{CDM}\) with variable tensor-to-scalar ratio \(r\).
  • _nu: \(\Lambda\mathrm{CDM}\) with three massive neutrinos, sampling over the lightest neutrino mass \(m_\mathrm{light}\) and the squared mass splittings \(\delta m^2\) and \(\Delta m^2\).
  • mcmc: Cobaya's Markov Chain Monte Carlo Metropolis sampler.

  • pc#d###: PolyChord run with #d repeats per parameter block (where d is the number of parameters in that block) and with ### live points.
    https://github.com/PolyChord/PolyChordLite/releases/tag/1.17.1
  • _class: theory code CLASS.
    https://github.com/lesgourg/class_public/releases/tag/v2.9.4
  • _p18_TTTEEElowTE_SZ: Planck 2018 TT,TE,EE+lowl+lowE data.
    https://pla.esac.esa.int/pla/#cosmology
  • _nufit50: NuFIT 5.0 data.
    http://www.nu-fit.org/?q=node/228
  • _NH and _IH: normal and inverted neutrino hierarchy.
  • _logr##: logarithmic sampling of tensor-to-scalar ratio \(r\) with lower log bound given .by log10r=-##.
  • _mdD: sampling over the lightest neutrino mass \(m_\mathrm{light}\) and the squared mass splittings \(\delta m^2\) and \(\Delta m^2\) (medium and heavy neutrino mass are derived parameters) with mass units in eV.
  • _logmdD##: logarithmic (instead of uniform) sampling of the lightest neutrino mass \(m_\mathrm{light}\) with lower log bound given by log10mlight=-##.
