Dark Radiation after Planck
Najla Said, Eleonora Di Valentino, Martina Gerbino
We present new constraints on the relativistic neutrino effective number N_eff and on the Cosmic Microwave Background power spectrum lensing amplitude A_L from the recent Planck 20…
Dark Radiation candidates after Planck
Eleonora Di Valentino, Alessandro Melchiorri, Olga Mena
Recent Cosmic Microwave Background (CMB) results from the Planck satellite, combined with previous CMB data and Hubble constant measurements from the Hubble Space Telescope, provid…
Neutrino Anisotropies after Planck
Martina Gerbino, Eleonora Di Valentino, Najla Said
We present new constraints on the rest-frame sound speed, c_{eff}^2, and the viscosity parameter, c_{vis}^2, of the Cosmic Neutrino Background from the recent measurements of the C…
Tickling the CMB damping tail: scrutinizing the tension between the ACT and SPT experiments
Eleonora Di Valentino, Silvia Galli, Massimiliano Lattanzi +4
The Atacama Cosmology Telescope (ACT) and the South Pole Telescope (SPT) have recently provided new, very precise measurements of the cosmic microwave background (CMB) anisotropy d…
