Constraints on the Pre-Big Bang scenario from a cosmological interpretation of the NANOGrav data
P. Conzinu, G. Fanizza, M. Gasperini +3
We discuss a recently proposed fit of the 15-year data set obtained from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) in terms of a relic stochastic…

Primordial Black Holes from Pre-Big Bang inflation
P. Conzinu, M. Gasperini, G. Marozzi
We discuss the possibility of producing a significant fraction of dark matter in the form of primordial black holes in the context of the pre-big bang inflationary scenario. We tak…
