This work deals with the search for signatures of non-Gaussianities in the cosmic microwave background (CMB) and adapts complementary methods stemming from the field of complexity science to CMB data analysis.

This workdeals with the search for signatures of non-Gaussianities in the cosmic microwave background (CMB). Probing Gaussianity in the CMB addresses one of the key questions in modern cosmology because it allows us to discriminate between different models of inflation, and thus concerns a fundamental part of the standard cosmological model.
The basic goalhere is to adapt complementary methods stemming from the field of complexity science to CMB data analysis. Two key concepts, namely the method of surrogates and estimators for local scaling properties, are applied to CMB data...
