Novel Constraints on Mixed Dark-Matter Scenarios of Primordial Black Holes and WIMPs
Sofiane M. Boucenna, Florian Kuhnel, Tommy Ohlsson +1
We derive constraints on mixed dark-matter scenarios consisting of primordial black holes (PBHs) and weakly interacting massive particles (WIMPs). In these scenarios, we expect a d…

Observational Constraints on Monomial Warm Inflation
Luca Visinelli
Warm inflation is, as of today, one of the best motivated mechanisms for explaining an early inflationary period. In this paper, we derive and analyze the current bounds on warm in…

Inflating without a flat potential: Viscous inflation
Luca Visinelli
Bulk viscosity leads to negative pressure, which is a key ingredient for successful inflation. We build an inflationary model where the slow-roll of the inflaton field is driven by…
