60. New probe for non-Gaussianities with primordial black hole induced gravitational waves

Theodoros Papanikolaou

2/14/24, 3:45 PM

We propose a new probe of primordial non-Gaussianities through
the observational window of gravitational waves (GW) being induced by
ultra-light ($M_{\text{PBH}}< 10^{9}\rm{g}$) primordial black holes
(PBHs). An existence of primordial non-Gaussianity can leave imprints on
the clustering properties of PBHs and the spectral shape of the induced
GW signal. Focusing on local-type...
