Linking multipole vectors and pseudoentropies for CMB analysis
Marvin Pinkwart, Peter Schupp, Dominik J. Schwarz
Multipole vectors and pseudoentropies provide powerful tools for a numerically fast and vivid investigation of possible statistically anisotropic, respectively non-Gaussian signs i…

Entropy methods for CMB analysis of anisotropy and non-Gaussianity
Momchil Minkov, Marvin Pinkwart, Peter Schupp
We propose several pseudoentropy measures that agree well with the Wehrl entropy, but are significantly faster to compute. All of them are rotationally invariant measures of entang…

Multipole vectors of completely random microwave skies for
Marvin Pinkwart, Dominik J. Schwarz
The statistical cosmological principle states that observables on the celestial sphere are sampled from a rotationally invariant distribution. Previously certain large scale anomal…
