Asymptotic Generation of Kerr Geometry from Schwarzschild via BMS Supertranslations
Nihar Ranjan Ghosh, Malay K. Nandy
The Bondi-van der Burg-Metzner-Sachs (BMS) group, as the asymptotic symmetry group of asymptotically flat spacetimes, plays a central role in connecting infrared structures of grav…

Nonlinear Dynamics of the Inner Horizon in Reissner-Nordström Black Holes: Insights into Mass Inflation
Nihar Ranjan Ghosh, Malay K. Nandy
The well-known instability of the inner horizon of a Reissner-Nordström black hole, first suggested by Simpson and Penrose, although studied extensively, has remained illusive so f…

Mass Superinflation from Enhanced Cauchy Horizon Singularity in a Reissner-Nordström Black Hole
Nihar Ranjan Ghosh, Malay K. Nandy
Ever since Penrose and Simpson contradicted Novikov's prediction that an infalling passenger would emerge into an asymptotically flat universe, there have been a continued interest…
