Perturbations of Schwarzschild black holes in the Lorenz gauge: Formulation and numerical implementation
Abstract
We reformulate the theory of Schwarzschild black hole perturbations in terms of the metric perturbation in the Lorenz gauge. In this formulation, each tensorharmonic mode of the perturbation is constructed algebraically from ten scalar functions, satisfying a set of ten wavelike equations, which are decoupled at their principal parts. We solve these equations using numerical evolution in the time domain, for the case of a pointlike test particle set in a circular geodesic orbit around the black hole. Our code uses characteristic coordinates, and incorporates a constraintdamping scheme. The axially symmetric, oddparity modes of the perturbation are obtained analytically. The approach developed here is especially advantageous in applications requiring knowledge of the local metric perturbation near a point particle; in particular, it offers a useful framework for calculations of the gravitational selfforce.

We study perturbations of a Schwarzschild black hole in ChernSimons modified gravity. We begin by showing that Birkhoff's theorem holds for a wide family of ChernSimons coupling functions, a scalar field present in the theory that controls the strength of the ChernSimons correction to the EinsteinHilbert action. After decomposing the perturbations in spherical harmonics, we study the linearized modified field equations and find that axial and polar modes are coupled, in contrast to general relativity. The divergence of the modified equations leads to the Pontryagin constraint, which forces the vanishing of the CunninghamPriceMoncrief master function associated with axial modes. Wemore »

Perturbations of Schwarzschild black holes in dynamical ChernSimons modified gravity
Dynamical ChernSimons modified gravity is an attractive, yet relatively unexplored, candidate to an alternative theory of gravity. The dynamical ChernSimons correction couples a dynamical scalar field to the gravitational field. In this framework, we analyze the perturbation formalism and stability properties of spherically symmetric black holes. Assuming that no background scalar field is present, gravitational perturbations with polar and axial parities decouple. We find no effect of the ChernSimons coupling on the polar sector, while axial perturbations couple to the ChernSimons scalar field. The axial sector can develop strong instabilities if the coupling parameter {beta}, associated to the dynamical couplingmore » 
Complete gaugeinvariant formalism for arbitrary secondorder perturbations of a Schwarzschild black hole
Using recently developed efficient symbolic manipulations tools, we present a general gaugeinvariant formalism to study arbitrary radiative (l{>=}2) secondorder perturbations of a Schwarzschild black hole. In particular, we construct the secondorder Zerilli and ReggeWheeler equations under the presence of any two firstorder modes, reconstruct the perturbed metric in terms of the master scalars, and compute the radiated energy at null infinity. The results of this paper enable systematic studies of generic secondorder perturbations of the Schwarzschild spacetime, in particular, studies of modemode coupling and nonlinear effects in gravitational radiation, the secondorder stability of the Schwarzschild spacetime, or the geometry ofmore » 
Gauge invariant perturbations of black holes. II. Kerr space{endash}time
We cast the perturbed Bianchi identities into a form involving only tetrad and coordinategauge invariant field quantities. From the perturbed Bianchi identities we then derive a system of gauge invariant wavelike gravitational perturbation equations. These are the Teukolsky equation, a gauge invariant analog of the Regge{endash}Wheeler equation, and a new gravitational perturbation equation. The Bianchi identities also provide the transformations between the perturbation equations. In particular, the transformation between the Teukolsky equation and the analog of the Regge{endash}Wheeler equation arises in this way. This work extends our previous analysis of the perturbations of the Schwarzschild black hole to the Kerrmore »
