DESCRIPTION:Primordial black holes (PBHs) can generically form through the
  collapse of enhanced cosmological perturbations\, constituting in some sp
 ecific mass ranges a viable candidate for dark matter. Interestingly enoug
 h\, the enhanced cosmological perturbations which collapse to form PBHs as
  well as the PBH energy density perturbations themselves can produce a sto
 chastic gravitationalwave (GW) background induced by second-order gravitat
 ional interactions\, which can be detectable in GW observatories. In this 
 talk\, after introducing initially the motivation for the physics of PBHs 
 and the associated to them GW signals I will focus afterwards on the ultra
 -light PBH mass range and its induced GW signatures through which one can 
 probe the physics of the primordial Universe. Finally\, I will discuss as 
 well GWs induced by vector metric perturbations sourced by primordial magn
 etic fields.
