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…
Bounds on the charge of the graviton using gravitational wave observations
Sreejith Nair, Aditya Vijaykumar, Sudipta Sarkar
If the graviton possesses a non-zero charge , gravitational waves (GW) originating from astrophysical sources would experience an additional time delay due to intergalactic ma…
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…
Asymptotically de-Sitter black holes have non-zero tidal Love numbers
Sreejith Nair, Sumanta Chakraborty, Sudipta Sarkar
Love numbers of compact objects quantify their tidal deformability against external perturbations. It is expected that Love numbers of asymptotically flat black holes (BHs) in Gene…
