Non-Gaussianity in three fluid curvaton model
Tuomas Multamaki, Jani Sainio, Iiro Vilja
The generation of non-gaussianity is studied in a three fluid curvaton model. By utilizing second order perturbation theory we derive general formulae for the large scale temperatu…

Suppression of the large scale curvature perturbation by interacting fluids
T. Multamaki, J. Sainio, I. Vilja
The large-scale dynamics of a two-fluid system with a time dependent interaction is studied analytically and numerically. We show how a rapid transition can significantly suppress…
