The performance of spherical wavelets to detect non-Gaussianity in the cosmic microwave background sky
Monthly Notices of the Royal Astronomical Society, no. 1 (2002): 22-32
EI WOS
摘要
We investigate the performance of spherical wavelets in discriminating between standard inflationary (Gaussian) and non-Gaussian models. For the latter we consider small perturbations of the Gaussian model in which an artificially specified skewness or kurtosis is introduced through the Edgeworth expansion. By combining all the informatio...更多
