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…
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…
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…
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…
Rotating black hole solutions for gravity and Newman Janis Algorithm
Pankaj Chaturvedi, Utkarsh Kumar, Udaykrishna Thattarampilly +1
We show that the -gravity theories with constant Ricci scalar in the Jordan/Einstein frame can be described by Einstein or Einstein-Maxwell gravity with a cosmological term a…
Gravitational Wave Heating
Vishnu Kakkat, Nigel T. Bishop, Amos S. Kubeka
It was shown in previous work that when a gravitational wave (GW) passes through a viscous shell of matter the magnitude of the GW will be damped and there are astrohysical circums…
