Non-Gaussianity from Particle Production during Inflation
Figure 10
Marginalized posterior likelihood contours for the parameters and (the magnitude and position of the feature, resp.) in the single-bump model. Black and grey regions correspond to parameter values allowed at 95.4% and 99.7% confidence levels, respectively. At small scales, to the right of the dashed vertical line, our results should be taken with a grain of salt since the nonlinear evolution of the power spectrum may not be modeled correctly in the presence of bump-like distortions.
