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…

Birkhoff's Theorem and Uniqueness: A Peek Beyond General Relativity

Rajes Ghosh, Akash K Mishra, Avijit Chowdhury

In General Relativity, Birkhoff's theorem asserts that any spherically symmetric vacuum solution must be static and asymptotically flat. In this paper, we study the validity of Bir…

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…

Exploring Ladder Symmetry and Love Numbers for Static and Rotating Black Holes

Chanchal Sharma, Rajes Ghosh, Sudipta Sarkar

Black hole solutions of general relativity exhibit a symmetry for the static perturbations around these spacetimes, known as "ladder symmetry". This symmetry proves useful in const…
