Modulated preheating and isocurvature perturbations
Kari Enqvist, Stanislav Rusak
We consider a model of preheating where the coupling of the inflaton to the preheat field is modulated by an additional scalar field which is light during inflation. We establish t…

Constraints on scalar and tensor perturbations in phenomenological and two-field inflation models: Bayesian evidences for primordial isocurvature and tensor modes
Jussi Valiviita, Matti Savelainen, Marianne Talvitie +2
We constrain cosmological models where the primordial perturbations have both an adiabatic and a (possibly correlated) cold dark matter (CDM) or baryon isocurvature component. We u…
