Recent gravitational wave observation by pulsar timing arrays and primordial black holes: The importance of non-Gaussianities

G Franciolini, AJ Iovino, V Vaskonen, H Veermäe - Physical Review Letters, 2023 - APS
We study whether the signal seen by pulsar timing arrays (PTAs) may originate from
gravitational waves (GWs) induced by large primordial perturbations. Such perturbations …
