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…

Late universe dynamics with scale-independent linear couplings in the dark sector

Claudia Quercellini, Marco Bruni, Amedeo Balbi +1

We explore the dynamics of cosmological models with two coupled dark components with energy densities and . We assume that the coupling is of the form , s…
