Damping of primordial gravitational waves from generalized sources

Dent, James B; Krauss, Lawrence; Sabharwal, Subir; Vachaspati, Tanmay


It has been shown that a cosmological background with an anisotropic stress tensor, appropriate for a free-streaming thermal neutrino background, can damp primordial gravitational waves after they enter the horizon, and can thus affect the cosmic microwav
