Testing for double inflation with WMAP

David Parkinson, Shinji Tsujikawa, Bruce A. Bassett +1

With the WMAP data we can now begin to test realistic models of inflation involving multiple scalar fields. These naturally lead to correlated adiabatic and isocurvature (entropy)…

Observational constraints on patch inflation in noncommutative spacetime

Gianluca Calcagni, Shinji Tsujikawa

We study constraints on a number of patch inflationary models in noncommutative spacetime using a compilation of recent high-precision observational data. In particular, the four-d…

Observational constraints on braneworld inflation: the effect of a Gauss-Bonnet term

Shinji Tsujikawa, M. Sami, Roy Maartens

High-energy modifications to general relativity introduce changes to the perturbations generated during inflation, and the latest high-precision cosmological data can be used to pl…
