[Journal club]Inflationary primordial black holes for the LIGO gravitational wave events and pulsar timing array (PTA) experiments - Inomata et al. (2017)

Curtis Chang

We discuss the possibility to interpret the observed LIGO gravitational wave (GW) events, via second-order effect, as mergers of primordial black hokes (PBHs) which are generated by cosmic inflation from large primordial density perturbations.
