Constraints on Primordial Non-Gaussianity from a Needlet Analysis of the WMAP-5 Data
Davide Pietrobon, Paolo Cabella, Amedeo Balbi +2
We look for a non-Gaussian signal in the WMAP 5-year temperature anisotropy maps by performing a needlet-based data analysis. We use the foreground-reduced maps obtained by the WMA…
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…
Map-making in small field modulated CMB polarisation experiments: approximating the maximum-likelihood method
D. Sutton, B. R. Johnson, M. L. Brown +3
Map-making presents a significant computational challenge to the next generation of kilopixel CMB polarisation experiments. Years worth of time ordered data (TOD) from thousands of…
Detecting the B-mode Polarisation of the CMB with Clover
C. E. North, B. R. Johnson, P. A. R. Ade +41
We describe the objectives, design and predicted performance of Clover, which is a ground-based experiment to measure the faint ``B-mode'' polarisation pattern in the cosmic microw…
Harmonic Inpainting of the Cosmic Microwave Background Sky: Formulation and Error Estimate
Kaiki Taro Inoue, Paolo Cabella, Eiichiro Komatsu
We develop a new interpolation scheme, based on harmonic inpainting, for reconstructing the cosmic microwave background temperature data within the Galaxy mask from the data outsid…
Spherical Needlets for CMB Data Analysis
D. Marinucci, D. Pietrobon, A. Balbi +6
We discuss Spherical Needlets and their properties. Needlets are a form of spherical wavelets which do not rely on any kind of tangent plane approximation and enjoy good localizati…
