Bayesian evidence for the tensor-to-scalar ratio and neutrino masses : Effects of uniform vs logarithmic priors
Lukas T. Hergt, Will J. Handley, Michael P. Hobson +1
We review the effect that the choice of a uniform or logarithmic prior has on the Bayesian evidence and hence on Bayesian model comparisons when data provide only a one-sided bound…
Quantum initial conditions for inflation and canonical invariance
F. J. Agocs, L. T. Hergt, W. J. Handley +2
We investigate the transformation of initial conditions for primordial curvature perturbations under two types of transformations of the associated action: simultaneous redefinitio…
Constraining the kinetically dominated Universe
L. T. Hergt, W. J. Handley, M. P. Hobson +1
We present cosmological constraints from Planck 2015 data for a universe that is kinetically dominated at very early times. We perform a Markov chain Monte Carlo analysis to estima…
A case for kinetically dominated initial conditions for inflation
L. T. Hergt, W. J. Handley, M. P. Hobson +1
We make a case for setting initial conditions for inflation at the Planck epoch in the kinetically dominated regime. For inflationary potentials with a plateau or a hill, i.e. pote…
