Primordial non-Gaussianity as a saviour for PBH overproduction in SIGWs generated by Pulsar Timing Arrays for Galileon inflation

Sayantan Choudhury, Kritartha Dey, Ahaskar Karde +2

We investigate the explicit role of negative local non-Gaussianity, $f_{\mathrm{NL}}$, in suppressing the abundance of primordial black holes (PBHs) in the single-field model of Galileo…
