High accuracy simulations of Kerr tails: coordinate dependence and higher multipoles
Manuel Tiglio, Lawrence Kidder, Saul Teukolsky
We investigate the late time behavior of a scalar field on a fixed Kerr background using a 2+1 dimensional pseudospectral evolution code. We compare evolutions of pure axisymmetric…
Excision without excision: the relativistic turducken
David Brown, Olivier Sarbach, Erik Schnetter +4
to turducken (turduckens, turduckening, turduckened, turduckened) [math.]: To stuff a black hole. We analyze and apply an alternative to black hole excision based on smoothing the…
How far away is far enough for extracting numerical waveforms, and how much do they depend on the extraction method?
Enrique Pazos, Ernst Nils Dorband, Alessandro Nagar +3
We present a method for extracting gravitational waves from numerical spacetimes which generalizes and refines one of the standard methods based on the Regge--Wheeler--Zerilli pert…
Boundary conditions for Einstein's field equations: Analytical and numerical analysis
Olivier Sarbach, Manuel Tiglio
Outer boundary conditions for strongly and symmetric hyperbolic formulations of 3D Einstein's field equations with a live gauge condition are discussed. The boundary conditions hav…
Dynamical control of the constraints growth in free evolutions of Einstein's equations
Manuel Tiglio
I present a new, simple method to dynamically control the growth of the discretized constraints during a free evolution of Einstein's equations. During an evolution, any given fami…
