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:

Perturbations of stealth black holes in degenerate higher-order scalar-tensor theories
TL;DR: In this paper, the authors investigate the physical perturbations about the Schwarzschild-de Sitter black holes and find that the odd-parity tensor perturbation behaves in a way indistinguishable to general relativity.
Journal ArticleDOI
Gravitation, the Quantum and Bohr's Correspondence Principle
TL;DR: In this article, the authors used Bohr's correspondence principle to prove that the area-entropy-thermodynamic relation for black holes is 4h ln 3, consistent with the Boltzmann-Einstein formula in statistical physics.

Accurate gravitational waveforms for binary-black-hole mergers with nearly extremal spins
TL;DR: In this article, the authors present numerical waveforms from simulations of merging black holes with the highest spins simulated to date: a 25.5-orbit inspiral, merger, and ringdown of two holes with equal masses and spins of magnitude 0.97 aligned with the orbital angular momentum.

A geometric framework for black hole perturbations
TL;DR: In this paper, the authors proposed a framework for the representation of quasinormal mode eigenfunctions and the construction of short-ranged potentials for the perturbation equations in frequency domain.

Decay of the Maxwell field on the Schwarzschild manifold
TL;DR: In this paper, the decay rate of the decoupled Maxwell equations in the exterior region of a Schwarzschild black hole was studied and the authors used vector field methods and did not require a spherical harmonic decomposition.
