Non-Gaussian spectra in cosmic microwave background temperature anisotropies
Gaussian cosmic microwave background skies are fully specified by the power spectrum. The conventional method of characterizing non-Gaussian skies is to evaluate higher order moments, the n -point functions, and their Fourier transforms. We argue that this method is inefficient, due to the redundan...
