Updated Constraints and Forecasts on Primordial Tensor Modes
Giovanni Cabass, Luca Pagano, Laura Salvati +3
We present new, tight, constraints on the cosmological background of gravitational waves (GWs) using the latest measurements of CMB temperature and polarization anisotropies provid…
New constraints on primordial gravitational waves from Planck 2015
Luca Pagano, Laura Salvati, Alessandro Melchiorri
We show that the new precise measurements of Cosmic Microwave Background (CMB) temperature and polarization anisotropies made by the Planck satellite significantly improves previou…
Constraints on the Early and Late Integrated Sachs-Wolfe effects from Planck 2015 Cosmic Microwave Background Anisotropies angular power spectra
Giovanni Cabass, Martina Gerbino, Elena Giusarma +3
The Integrated Sachs-Wolfe (ISW) effect predicts additional anisotropies in the Cosmic Microwave Background due to time variation of the gravitational potential when the expansion…
Planck 2015 results. XI. CMB power spectra, likelihoods, and robustness of parameters
Planck Collaboration, N. Aghanim, M. Arnaud +221
This paper presents the Planck 2015 likelihoods, statistical descriptions of the 2-point correlations of CMB data, using the hybrid approach employed previously: pixel-based at $\e…
