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:

Analogue Gravity
TL;DR: Analogous gravity is a research programme which investigates analogues of general relativistic gravitational fields within other physical systems, typically but not exclusively condensed matter systems, with the aim of gaining new insights into their corresponding problems.

The Motion of Point Particles in Curved Spacetime
TL;DR: In this article, a review of the mathematical tools required to derive the equations of motion of a point scalar charge, a point electric charge, and a point mass in a specified background spacetime is presented.
Journal ArticleDOI
An analytic representation for the quasi-normal modes of Kerr black holes
TL;DR: In this paper, the gravitational quasi-normal frequencies of both stationary and rotating black holes are calculated by constructing exact eigensolutions to the radiative boundary-value problem of Chandrasekhar and Detweiler.
Journal ArticleDOI
Tidal Love numbers of neutron stars
TL;DR: For a variety of fully relativistic polytropic neutron star models, the authors calculated the star's tidal Love number k2, which is potentially measurable in gravitational wave signals from inspiralling binary neutron stars.

Quasinormal modes: the characteristic `sound' of black holes and neutron stars
TL;DR: In this paper, the authors summarize how quasinormal modes are defined and computed, see why they have been regarded as closely analogous to normal modes, and discover why they are actually quite different.
