Spin Wavelets on the Sphere
Daryl Geller, Domenico Marinucci
In recent years, a rapidly growing literature has focussed on the construction of wavelet systems to analyze functions defined on the sphere. Our purpose in this paper is to genera…
Spin Needlets for Cosmic Microwave Background Polarization Data Analysis
Daryl Geller, Frode K. Hansen, Domenico Marinucci +2
Scalar wavelets have been used extensively in the analysis of Cosmic Microwave Background (CMB) temperature maps. Spin needlets are a new form of (spin) wavelets which were introdu…
Needlet Detection of Features in WMAP CMB Sky and the Impact on Anisotropies and Hemispherical Asymmetries
Davide Pietrobon, Alexandre Amblard, Amedeo Balbi +3
We apply spherical needlets to the Wilkinson Microwave Anisotropy Probe 5-year cosmic microwave background (CMB) dataset, to search for imprints of non-isotropic features in the CM…
Representations of SO(3) and angular polyspectra
Domenico Marinucci, Giovanni Peccati
We characterize the angular polyspectra, of arbitrary order, associated with isotropic fields defined on the sphere S^2. Our techniques rely heavily on group representation theory,…
Statistical challenges in the analysis of Cosmic Microwave Background radiation
Paolo Cabella, Domenico Marinucci
An enormous amount of observations on Cosmic Microwave Background radiation has been collected in the last decade, and much more data are expected in the near future from planned o…
On The Dependence Structure of Wavelet Coefficients for Spherical Random Fields
Xiaohong Lan, Domenico Marinucci
We consider the correlation structure of the random coefficients for a wide class of wavelet systems on the sphere (Mexican needlets) which were recently introduced in the literatu…
The needlets bispectrum
Xiaohong Lan, Domenico Marinucci
The purpose of this paper is to join two different threads of the recent literature on random fields on the sphere, namely the statistical analysis of higher order angular power sp…
