Gravitational Wave Propagation through Viscous Matter
Vishnu Kakkat, Ulrich K. Beckering Vinckers, Nigel T. Bishop +4
It has been known that gravitational waves (GWs) transfer energy to viscous matter through which they propagate, but the effect is too weak to be astrophysically significant. Using…

Astrophysical and cosmological scenarios for gravitational wave heating
Nigel T. Bishop, Vishnu Kakkat, Amos S. Kubeka +2
Gravitational waves (GWs) passing through a viscous shell of matter are expected to be damped resulting in an increase in the temperature of the fluid as energy is transferred to i…

The interaction of gravitational waves with matter
Nigel T. Bishop, Vishnu Kakkat, Amos S. Kubeka +2
It is well-known that gravitational waves undergo no absorption or dissipation when traversing through a perfect fluid. However, in the presence of a viscous fluid, GWs transfer en…
