Looking for non-Gaussianity in the COBE-DMR data with spherical wavelets
R. B. Barreiro, M. P. Hobson, A. N. Lasenby +3
We present an analysis of the Gaussianity of the 4-year COBE-DMR data (in HEALPix pixelisation) based on spherical wavelets. The skewness, kurtosis and scale-scale correlation spec…
