Abstract

Primordial black holes are a unique probe of the early Universe and offer a potential link between inflationary dynamics and dark matter. In a recent work \citeInui:2024fgk, we analyse PBH formation and the associated stochastic gravitational wave background from scalar induced gravitational waves, while taking into account the contributions from local non-Gaussianities. We highlight the observable consequences for the LISA and PTA experiments.
