Universal Non-Gaussian Signatures from Transient Instabilities
Shuntaro Aoki, Diederik Roest, Denis Werth
We identify universal signatures in the bispectrum arising from a transient tachyonic instability of entropic fluctuations during inflation, a phenomenon that naturally arises in h…
Primordial Sharp Features through the Nonlinear Regime of Structure Formation
Clément Stahl, Denis Werth, Vivian Poulin
Sudden violations of the slow-roll regime during inflation, a natural prediction of many UV-complete inflationary models, give rise to sharp features in the primordial power spectr…
Reconstructing Primordial Curvature Perturbations via Scalar-Induced Gravitational Waves with LISA
Jonas El Gammal, Aya Ghaleb, Gabriele Franciolini +17
Many early universe scenarios predict an enhancement of scalar perturbations at scales currently unconstrained by cosmological probes. These perturbations source gravitational wave…
CosmoFlow: Python Package for Cosmological Correlators
Denis Werth, Lucas Pinol, Sébastien Renaux-Petel
Cosmological correlators hold the key to high-energy physics as they probe the earliest moments of our Universe, and conceal hidden mathematical structures. However, even at tree-l…
The Cosmological Flow: A Systematic Approach to Primordial Correlators
Lucas Pinol, Sébastien Renaux-Petel, Denis Werth
The time evolution of primordial fluctuations conceals a wealth of insights into the high-energy physics at play during the earliest moments of our Universe, which is ultimately en…
