Inhomogeneous reheating scenario with low scale inflation and/or MSSM flat directions
Marieke Postma
We discuss the constraints on the inhomogeneous reheating scenario. In particular, we discuss the prospects for low scale inflation with a Hubble constant of the order of the gravi…

Constraining the curvaton scenario
Marieke Postma
We analyse the curvaton scenario in the context of supersymmetry. Supersymmetric theories contain many scalars, and therefore many curvaton candidates. To obtain a scale invariant…

Challenges in generating density perturbations from a fluctuating inflaton coupling
Kari Enqvist, Anupam Mazumdar, Marieke Postma
We discuss the possibility of generating adiabatic density perturbations from spatial fluctuations in the inflaton decay rate which are due to quantum fluctuations of light moduli…
