Spectator Axions in String Inflation and Primordial Black Holes
Michele Cicoli, Dario L. Lorenzoni, Evan McDonough +1
We study the impact of light spectator axions on the seeding of primordial black holes (PBHs) during inflation in string theory. Primordial black holes exhibit unique and novel phe…

Nonthermal leptogenesis via cosmological gravitational particle production is tested by inflationary gravitational waves
Tammi Chowdhury, Leah Jenks, Edward W. Kolb +2
We explore the coincidence of scales between cosmic inflation and right-handed neutrinos in seesaw models. We show that inflation models, which will be tested by next-generation CM…
