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…
Affine parameterization of the dark sector: costraints from WMAP5 and SDSS
Davide Pietrobon, Amedeo Balbi, Marco Bruni +1
We study a set of universe models where the dark sector is described by a perfect fluid with an affine equation of state , focusing specifically on cosmological perturbat…
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…
Dark Energy Constraints from Needlets Analysis of Wmap3 and NVSS Data
Davide Pietrobon, Amedeo Balbi, Domenico Marinucci
We cross-correlate the new 3 year Wilkinson Microwave Anistropy Probe (WMAP3) cosmic microwave background (CMB) data with the NRAO VLA Sky Survey (NVSS) radio galaxy data, and find…
Integrated Sachs-Wolfe effect from the cross correlation of WMAP3 year and the NRAO VLA sky survey data: New results and constraints on dark energy
Davide Pietrobon, Amedeo Balbi, Domenico Marinucci
We cross-correlate the new 3 year Wilkinson Microwave Anistropy Probe (WMAP) cosmic microwave background (CMB) data with the NRAO VLA Sky Survey (NVSS) radio galaxy data, and find…
