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…

Exponential corrections to black hole entropy
Ayan Chatterjee, Amit Ghosh
Using the quasilocal properties alone we show that the area spectrum of a black hole horizon must be discrete, independent of any specific quantum theory of gravity. The area spect…

Marginally Trapped Surfaces in Spherical Gravitational Collapse
Ayan Chatterjee, Amit Ghosh, Suresh Jaryal
This paper deals with a detail study of gravitational collapse of dust and viscous fluids under the assumptions of spherical symmetry. Our main goal is to closely analyze the horiz…
