Making observable predictions for cosmic inflation requires
determining when the wavenumbers of astrophysical interest today
exited the Hubble radius during the inflationary epoch. These instants
are commonly evaluated using the slow-roll approximation and measured
in e-folds time. Pierre,
Baptiste and Christophe
propose a new analytical method to determine these instants with a
precision reaching the tenth of an e-fold.

What is the status of Cosmic Inflation given the latest cosmological
data? In a 80 pages-long publication, we present the first ever data
analysis using the third-order slow-roll power spectra complemented by
an unprecedented Bayesian model comparison in the landscape of nearly
three-hundred models of single-field slow-roll inflation.
