2.1 What is the abundance of PBHs?
2.2 What is the effect of PBH clustering?
2.3 What fraction of the currently observed GW events can be ascribed to PBHs?
3.3 Plugging the pair instability gap with PBH?
3.4 PBH eccentricity, 3.5 PBH spin and 3.6 Future gamma-ray telescopes
2 Some open questions
How well do we know the PBH abundance? And over what mass range? How well can we ascertain the PBH clustering properties and therefore the GW signal from binary mergers via LIGO and future terrestrial GW interferometers? And can we use the vicinities of SMBH amd IMBH, most likely rich in dark matter and where PBH abundances are in consequence likely to be enhanced, as potential sources of EMRI signals for experiments such as LISA? We briefly discuss such open theoretical and observational questions below.
