Correlation of isocurvature perturbation and non-Gaussianity
Jinn-Ouk Gong, Godfrey Leung
We explore the correlations between primordial non-Gaussianity and isocurvature perturbation. We sketch the generic relation between the bispectrum of the curvature perturbation an…
Probing reheating with primordial spectrum
Jinn-Ouk Gong, Shi Pi, Godfrey Leung
We study the impacts of reheating temperature on the inflationary predictions of the spectral index and tensor-to-scalar ratio. Assuming sinusoidal oscillations and that reheating…
Influence of Reheating on the Trispectrum and its Scale Dependence
Godfrey Leung, Ewan R. M. Tarrant, Christian T. Byrnes +1
We study the evolution of the non-linear curvature perturbation during perturbative reheating, and hence how observables evolve to their final values which we may compare against o…
Reheating, Multifield Inflation and the Fate of the Primordial Observables
Godfrey Leung, Ewan R. M. Tarrant, Christian T. Byrnes +1
We study the effects of perturbative reheating on the evolution of the curvature perturbation ζ, in two-field inflation models. We use numerical methods to explore the sensitivity…
