Constraining Galileon inflation
journal contribution
posted on 2023-06-09, 00:17 authored by Donough Regan, Gemma Jayne Anderson, Matthew Hull, David SeeryDavid SeeryIn this short paper, we present constraints on the Galileon inflationary model from the CMB bispectrum. We employ a principal-component analysis of the independent degrees of freedom constrained by data and apply this to the WMAP 9-year data to constrain the free parameters of the model. A simple Bayesian comparison establishes that support for the Galileon model from bispectrum data is at best weak.
