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…
Inflation from entropy
Udaykrishna Thattarampilly, Yunlong Zheng
We investigate cosmological solutions for the modified gravity theory obtained from quantum relative entropy between the metric of spacetime and the metric induced by the geometry…
Probe of spatial geometry from scalar induced gravitational waves
Utkarsh Kumar, Udaykrishna Thattarampilly, Pankaj Chaturvedi
We investigate a novel probe of spatial geometry of the Universe through the observation of gravitational waves (GWs) induced by first order curvature perturbations. The existence…
