Non-Gaussianity after many-field reheating
Pedro Carrilho, David Mulryne, John Ronayne
We numerically investigate reheating after quadratic inflation with up to 65 fields, focusing on the production of non-Gaussianity. We consider several sets of initial conditions,…

Turning in the landscape: a new mechanism for generating Primordial Black Holes
Jacopo Fumagalli, Sébastien Renaux-Petel, John W. Ronayne +1
We propose a new model-independent mechanism for producing primordial black holes from a period of multi-field inflation. This requires an enhancement of primordial fluctuations at…
