Mapping the large-angle deviation from Gaussianity in simulated CMB maps

Mapping the large-angle deviation from Gaussianity in simulated CMB maps

[Abridged] In recent works we have proposed two new large-angle non-Gaussianity indicators based on skewness and kurtosis of patches of CMB sky-sphere, and used them to find out significant deviation from Gaussianity in frequency bands and foreground-reduced CMB maps. Simulated CMB maps with assigned type and amplitude of primordial non-Gaussianity …
