Did NANOGrav see a signal from primordial black hole formation?. (arXiv:2009.07832v4 [astro-ph.CO] UPDATED)

We show that the recent NANOGrav result can be interpreted as a stochastic
gravitational wave signal associated to formation of primordial black holes
from high-amplitude curvature perturbations. The indicated amplitude and power
of the gravitational wave spectrum agrees well with formation of primordial
seeds for supermassive black holes.
