New constraints on primordial gravitational waves from Planck 2015
We show that the new precise measurements of Cosmic Microwave Background (CMB) temperature and polarization anisotropies made by the Planck satellite significantly improves previous constraints on the cosmic gravitational waves background (CGWB) at frequencies f>10−15 Hz. On scales smaller than t...
