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:

Black Hole Quasinormal Modes in the Era of LIGO
TL;DR: In this paper, the authors introduce the notion and analysis of black hole quasinormal modes, starting from the linear perturbation theory and including a brief discussion of numerical methods and astrophysical implications in the gravitational wave signals recently detected.

Effects of Schwarzschild black hole horizon on isothermal plasma wave dispersion
Muhammad Sharif,Umber Sheikh +1 more
TL;DR: In this article, the 3 + 1 GRMHD equations for Schwarzschild spacetime in Rindler coordinates with isothermal state of plasma are formulated and the determinant of these equations in each case leads to two dispersion relations which give value of the wave number k.

Axial quasinormal modes of static neutron stars in the nonminimal derivative coupling sector of Horndeski gravity: Spectrum and universal relations for realistic equations of state
TL;DR: In this paper, the axial quasinormal modes of static neutron stars in the nonminimal derivative coupling sector of Horndeski theory were analyzed for ten different equations of state with different matter content.

Spin and Quadrupole Contributions to the Motion of Astrophysical Binaries
TL;DR: In this article, it is shown that the corrections to geodesic motion due to spin (dipole), quadrupole, and higher multipoles can be modeled by an extension of the point mass action.

Perturbative and nonperturbative fermionic quasinormal modes of Einstein-Gauss-Bonnet-AdS black holes
TL;DR: In this article, the authors present the quasinormal modes of a fermionic field in the background of Gauss-Bonnet-AdS black holes and find exact solutions for some range of values of the coupling constant.
