We investigate the behavior of a dynamical scalar field on a fixed Kerr background in Kerr-Schild coordinates using a (3+1)-dimensional spectral evolution code, and we measure the power-law tail decay that occurs at late times. We compare evolutions of initial data proportional to f(r)Y[script l]m(theta,phi), where Y[script l]m is a spherical harmonic and (r,theta,phi) are Kerr-Schild coordinates, to that of initial data proportional to f(rBL)Y[script l]m(thetaBL,phi), where (rBL,thetaBL) are… Expand

Numerical investigation of the late-time Kerr tails
The late-time behavior of a scalar field on fixed Kerr background is examined in a numerical framework incorporating the techniques of conformal compactification and hyperbolic initial valueExpand
Late-time Kerr tails revisited
The decay rate of late-time tails in the Kerr spacetime has been the cause of numerous conflicting results, both analytical and numerical. In particular, there is much disagreement on whether theExpand
Numerical solution of the 2 + 1 Teukolsky equation on a hyperboloidal and horizon penetrating foliation of Kerr and application to late-time decays
In this work, we present a formulation of the Teukolsky equation for generic spin perturbations on the hyperboloidal and horizon penetrating foliation of Kerr recently proposed by R?cz and T?th. AnExpand
Hyperboloidal slices for the wave equation of Kerr?Schild metrics and numerical applications
We present new results from two codes, using finite differencing and pseudospectral methods for the wave equations in (3+1) dimensions. We use a hyperboloidal transformation, which allows directExpand
High accuracy simulations of Kerr tails: coordinate dependence and higher multipoles
We investigate the late-time behavior of a scalar field on a fixed Kerr background using a 2 + 1 dimensional pseudo-spectral evolution code. We compare evolutions of pure axisymmetric multipoles inExpand
Computing inspirals in Kerr in the adiabatic regime : I. The scalar case
A key source for LISA will be the inspiral of compact objects into massive black holes. Recently Mino has shown that in the adiabatic limit, gravitational waveforms for these sources can be computedExpand
Late-time tails in the Kerr spacetime
Outside a black hole, perturbation fields die off in time as 1/tn. For spherical holes n = 2l + 3 where l is the multipole index. In the nonspherical Kerr spacetime there is no coordinate-independentExpand
Three-dimensional Einstein-Klein-Gordon system in characteristic numerical relativity
We incorporate a massless scalar field into a 3-dimensional code for the characteristic evolution of the gravitational field. The extended 3-dimensional code for the Einstein–Klein–Gordon system isExpand
Spectral Methods for Numerical Relativity
This paper focuses on a class called spectral methods in which, typically, the various functions are expanded in sets of orthogonal polynomials or functions, and presents results obtained by various groups in the field of general relativity by means of spectral methods. Expand
On the use of multipole expansion in time evolution of nonlinear dynamical systems and some surprises related to superradiance
A new numerical method is introduced to study the problem of time evolution of generic nonlinear dynamical systems in four-dimensional spacetimes. It is assumed that the time level surfaces areExpand
