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:

Probing the equation of state of neutron star matter with gravitational waves from binary inspirals in light of GW170817: a brief review
TL;DR: The role of the tidal deformability parameter, its definition, computation, and relation to the equation of state was discussed in this article, where the dominant tidal GW imprints were most relevant for the event GW170817.

Black holes in Gauss-Bonnet and Chern-Simons-scalar theory
TL;DR: In this paper, the stability analysis of the Schwarzschild black hole in Gauss-Bonnet and Chern-Simons-scalar theory was carried out, where two quadratic scalar couplings were introduced.
Journal ArticleDOI
Fourth derivative gravity in the auxiliary fields representation and application to the black-hole stability
TL;DR: In this article, an auxiliary field formulation for the general fourth-order gravity on an arbitrary curved background is proposed and the case of a Ricci-flat background is elaborated in detail and it is shown that there is an equivalence with the standard metric formulation.

Gravitational instability of the inner static region of a Reissner-Nordström black hole
TL;DR: In this paper, the authors prove that the interior static region of Reissner-Nordstrom black holes is unstable under linear gravitational perturbations, by showing that field perturbation compactly supported within this region will generically excite a mode that grows exponentially in time.

Decoupling limit and throat geometry of non-susy D3 brane
Kuntal Nayek,Shibaji Roy +1 more
TL;DR: In this article, it has been shown that the non-susy D3 brane is the holographic dual of a non-gravitational (non-supersymmetric) gauge theory.
