Description

If Primordial Black Holes (PBHs) are formed due to an enhanced scalar-perturbation amplitude at small scales, their formation is inevitably accompanied by the generation of gravitational waves (GWs). Thanks to a coincidence of scales, LISA will be able to observe the GWs associated with the formation of asteroidal mass PBHs, which may constitute the entirety of the dark matter. We will review some recent progress on the characterization of such a signal, alongside the potential constraints LISA will set on the inflationary dynamics underlying these formation models.
