Viscous attenuation of gravitational waves propagating through an inhomogeneous background
Viscous attenuation of gravitational waves propagating through an inhomogeneous background
We consider the propagation of gravitational waves in the late-time Universe in the presence of matter distribution inhomogeneities, and we also consider the cosmic fluid to be viscous. In this work, we investigate the cumulative effect of inhomogeneities and viscosity of the cosmic-fluid on the observables associated with the sources …
