The interaction between gravitational waves and a viscous fluid shell on a Schwarzschild background
Nigel T. Bishop
Previous work has shown that the interaction between gravitational waves (GWs) and a shell of viscous matter leads to damping of the GWs and heating of the matter, and that these e…
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…
Quasinormal modes of a Schwarzschild black hole within the Bondi-Sachs framework
Bishop Mongwane, Sipho Nkele, Didam G. A. Duniya +1
Studies of quasinormal modes (QNMs) of black holes have a long and well established history. Predominantly, much research in this area has customarily focused on the equations give…
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…
