Laws of black hole mechanics in the Einstein-Gauss-Bonnet theory
Ayan Chatterjee, Sahil Devdutt, Avirup Ghosh
We extend the isolated horizon formalism to include rotating black holes arising in five dimensional Einstein-Gauss-Bonnet (EGB) theory of gravity, and derive the laws of black hol…
Gravitational Collapse in the EGB Gravity
Ayan Chatterjee, Avirup Ghosh, Suresh Jaryal
The Einstein- Gauss- Bonnet (EGB) gravity is an important modification of the Einstein theory of gravity and, for many gravitational phenomena, the Gauss- Bonnet (GB) correction te…
Inducing supertranslations: The membrane picture
Avirup Ghosh
Dynamical evolution of black holes may be studied perturbatively in the membrane picture. We study the case of a body freely falling into a black hole, in the Rindler approximation…
Dynamical horizons and Super-Translation transitions of the horizon
Ayan Chatterjee, Avirup Ghosh
A condition is defined which determines if a supertranslation is induced in the course of a general evolution from one isolated horizon phase to another via a dynamical horizon. Th…
On Super-Translation transition between Quasi-local Black holes
Amit Ghosh, Avirup Ghosh, Pritam Nanda
We re-explore the symmetries of a weakly isolated horizon (WIH) from the perspective of freedom in the choice of intrinsic data. The supertranslations are realized as additional sy…
Constraints on higher curvature gravity from time delay between GW170817 and GRB 170817A
Avirup Ghosh, Soumya Jana, Akash K Mishra +1
General relativity may be an effective theory with higher curvature correction terms in the action. Inclusion of these terms leads to exciting new possibilities, e.g., gravitationa…
