Non-Gaussianity from Axionic Curvaton
Masahiro Kawasaki, Takeshi Kobayashi, Fuminobu Takahashi
We study non-Gaussianity of density perturbations generated by an axionic curvaton, focusing on the case that the curvaton sits near the hilltop of the potential during inflation.…

Curvatons in Warped Throats
Takeshi Kobayashi, Shinji Mukohyama
We present a curvaton model from type IIB string theory compactified on a warped throat with approximate isometries. Considering an (anti-)D3-brane sitting at the throat tip as a p…

Conformal Inflation, Modulated Reheating, and WMAP5
Takeshi Kobayashi, Shinji Mukohyama
We investigate density perturbations generated through modulated reheating while inflation is driven by a conformally coupled scalar field. A large running of the spectral index is…
