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…

Gravitational wave interactions with a viscous fluid: Core collapse supernova, binary neutron star merger, and accretion around a black hole merger
Nigel T. Bishop, Vishnu Kakkat, Monos Naidoo
The interaction of gravitational waves (GWs) with matter is normally treated as being insignificant. However, recent work has shown that the interaction with a viscous fluid may be…

Spherically symmetric black holes in Gravity from Entropy and spontaneous emission
Udaykrishna Thattarampilly, Yunlong Zheng, Vishnu Kakkat
We investigate static and dynamical spherically symmetric black hole solutions within the Gravity from Entropy (GfE) framework. We derive and solve the modified vacuum field equati…
