Primary gravitational waves at high frequencies II: Emergence of the exponential cut-off in the power spectrum
Alipriyo Hoory, Jerome Martin, Arnab Paul +1
[Abridged] In slow roll inflation, the power spectrum (PS) of primary gravitational waves (PGWs) generated from the quantum vacuum rises as over wave numbers which never…

Vanilla Inflation Predicts Negative Running
Jerome Martin, Christophe Ringeval, Vincent Vennin
We show that the simplest, and currently favoured, theoretical realizations of cosmic inflation yield a sharp prediction for the running of the spectral index . Using…

Cosmic Inflation at the Crossroads
Jerome Martin, Christophe Ringeval, Vincent Vennin
The capability of Cosmic Inflation to explain the latest Cosmic Microwave Background and Baryonic Acoustic Oscillation data is assessed by performing Bayesian model comparison with…
