Ergodicity and Gaussianity for Spherical Random Fields
Domenico Marinucci, Giovanni Peccati
We investigate the relationship between ergodicity and asymptotic Gaussianity of isotropic spherical random fields, in the high-resolution (or high-frequency) limit. In particular,…
Spin Needlets Spectral Estimation
Daryl Geller, Xiaohong Lan, Domenico Marinucci
We consider the statistical analysis of random sections of a spin fibre bundle over the sphere. These may be thought of as random fields that at each point p in take as a val…
Directional Variations of the Non-Gaussianity Parameter f_NL
Øystein Rudjord, Frode K. Hansen, Xiaohong Lan +3
We investigate local variations of the primordial non-Gaussianity parameter f_NL in the WMAP data, looking for possible influence of foreground contamination in the full-sky estima…
An Estimate of the Primordial Non-Gaussianity Parameter f_NL Using the Needlet Bispectrum from WMAP
Oystein Rudjord, Frode K. Hansen, Xiaohong Lan +3
We use the full bispectrum of spherical needlets applied to the WMAP data of the cosmic microwave background as an estimator for the primordial non-Gaussianity parameter f_NL. We u…
