Constraints on cosmological viscosity and self interacting dark matter from gravitational wave observations

arXiv:1603.02635 · doi:10.1103/PhysRevD.95.103509

Abstract

It has been shown that gravitational waves propagate through ideal fluids without experiencing any dispersion or dissipation. However, if the medium has a non-zero shear viscosity , gravitational waves will be dissipated at a rate proportional to . We constrain dark matter and dark energy models with non-zero shear viscosity by calculating the dissipation of gravitational waves from GW150914 which propagate over a distance of Mpc through the dissipative fluid and comparing the data with the theoretical prediction. This provides a proof-of-principle demonstration of the fact that future observations gravitational waves at LIGO have the potential of better constraining the viscosity of dark matter and dark energy.
