Description

I will discuss an intermittent type of primordial non-Gaussianity that arises from modulated preheating models and inflationary models with non-perturbative features. The non-Gaussianity has little impact on global statistics of the Universe. It produces or helps produce rare objects, such as CMB cold/hot spots and supermassive black holes at high redshift. The environment of rare objects may be used to distinguish the model from statistical flukes.
