Distinguishing general relativity from Chern-Simons gravity using gravitational wave polarizations
Soham Bhattacharyya, S. Shankaranarayanan
Quasi-normal modes (QNMs) uniquely characterize the final black-hole. Till now, only the QNM frequency and damping time are used to test General relativity. In this work, we show e…

Quasinormal modes as a distinguisher between general relativity and f(R) gravity: Charged black-holes
Soham Bhattacharyya, S. Shankaranarayanan
The ring-down phase of black-hole perturbations is governed by the Quasi-Normal modes (QNM) and offer valuable insight into the nature of the objects emitting them. In General rela…
