Overcharging Extremal Rotating Black Holes
Shauvik Biswas, Amruta Sadhu, Sudipta Sarkar
In this work, we use the weak cosmic censorship conjecture(WCC) to constrain black hole solutions in modified gravity theories. While Wald showed that extremal Kerr-Newman black ho…

Probing Spacetime Symmetries Using Gravitational Wave Ringdown
Rajes Ghosh, Akash K Mishra, Sudipta Sarkar
The uniqueness and rigidity theorems assert that the asymptotically flat, vacuum, stationary rotating black hole solution in general relativity must be the Kerr solution, exhibitin…

Restoring Causality in Higher Curvature Gravity
Jose D. Edelstein, Rajes Ghosh, Alok Laddha +1
Incorporating higher curvature terms into gravity theories modifies the classical field equations, potentially leading to theoretical issues like Shapiro time advancements that vio…
