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