Stability of a Schwarzschild Singularity
TLDR
In this article, it was shown that a Schwarzschild singularity, spherically symmetrical and endowed with mass, will undergo small vibrations about the spherical form and therefore remain stable if subjected to a small nonspherical perturbation.Abstract:

Stability under scalar perturbations and quasinormal modes of 4D Einstein-Born-Infeld dilaton spacetime: Exact spectrum
TL;DR: In this article, the stability under scalar perturbations of the Reissner-Nordstrom black hole was studied and the quasinormal modes of the Einstein-Born-Infeld dilaton spacetime were computed in 1+3 dimensions.
Journal ArticleDOI
Perturbations and Stability of Black Ellipsoids
TL;DR: In this article, the perturbations of two classes of static black ellipsoid solutions of four dimensional vacuum Einstein equations were studied in the context of the one-dimensional inverse scattering theory and the analysis was performed in the approximation of small eccentricity deformations of the Schwarzschild solution.

Reconstruction of black hole metric perturbations from Weyl curvature: II. The Regge–Wheeler gauge
TL;DR: In this paper, the perturbation theory of rotating black holes is described in terms of Weyl scalars ψ4 and ψ0, each satisfying Teukolsky's complex master wave equation with spin s = 2, and respectively representing outgoing and ingoing radiation.

Quasinormal modes of slowly-rotating black holes in dynamical Chern-Simons gravity
TL;DR: In this paper , the authors consider a theory which modifies general relativity by introducing a scalar field coupled to a parity-violating curvature term known as dynamical Chern-Simons gravity and find strong evidence that these rotating black holes are linearly stable.

Distinguishing general relativity from Chern-Simons gravity using gravitational wave polarizations
TL;DR: In this article, a consistent test for General relativity by considering Chern-Simons gravity was provided by considering the polarization of quasi-normal modes (QNMs) of the final black-hole.
