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…
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…
