Static tidal Love numbers of Schwarzschild and non-Schwarzschild black holes in quadratic gravity
Soham Bhattacharyya
We calculate the static electric quadrupolar response of black holes in four-dimensional quadratic gravity, with action . The Schwarzschild solution has zero massless…
On the equivalence between theories and Einstein gravity
Soham Bhattacharyya
In this brief note we present a somewhat trivial result. Namely, we show that perturbative off-shell -theory is equivalent to Einstein gravity, as well as to the Brans-Dicke…
Two body dynamics in a quadratic modification of general relativity
Soham Bhattacharyya
It is shown in this study that deviations from the Einstein-Hilbert action at the quadratic level using a proper analyses and suitable dynamical variables lead to a tiny modificati…
The Equivalence and/or the Effacing principle in theories of gravity
Soham Bhattacharyya
The Einstein-Hilbert action of general theory of relativity (GR) is the integral of the scalar curvature . It is a theory that is drawn from the Equivalence principle, and has p…
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…
Quasinormal modes as a distinguisher between general relativity and f(R) gravity
Soham Bhattacharyya, S. Shankaranarayanan
Quasi-Normal Modes (QNM) or ringdown phase of gravitational waves provide critical information about the structure of compact objects like Black Holes. Thus, QNMs can be a tool to…
