2.3 What fraction of the currently observed GW events can be ascribed to PBHs?
Thanks to the many binary BH events detected so far with many more expected in the next few years, gravitational-wave astronomy is about to become a population study. Currently hierarchical Bayesian analysis combining astrophysical formation models and PBHs may only constrain the fraction of a putative subpopulation of PBHs in the data (see for instance Ref. [13]). The exciting possibility that PBHs are contributing to current observations will be verified only by further reducing uncertainties in astrophysical and primordial formation models. This is another fundamental open issue.
