Spacelike matching to null infinity
Anil Zenginoglu, Manuel Tiglio
We present two methods to include the asymptotic domain of a background spacetime in null directions for numerical solutions of evolution equations so that both the radiation extra…
Gravitational perturbations of Schwarzschild spacetime at null infinity and the hyperboloidal initial value problem
Anil Zenginoglu, Dario Nunez, Sascha Husa
We study gravitational perturbations of Schwarzschild spacetime by solving a hyperboloidal initial value problem for the Bardeen-Press equation. Compactification along hyperboloida…
Hyperboloidal evolution with the Einstein equations
Anil Zenginoglu
We consider an approach to the hyperboloidal evolution problem based on the Einstein equations written for a rescaled metric. It is shown that a conformal scale factor can be freel…
A hyperboloidal study of tail decay rates for scalar and Yang-Mills fields
Anıl Zenginoğlu
We investigate the asymptotic behavior of spherically symmetric solutions to scalar wave and Yang-Mills equations on a Schwarzschild background. The studies demonstrate the astroph…
Hyperboloidal foliations and scri-fixing
Anıl Zenginoğlu
We discuss a gauge choice which allows us to avoid the introduction of artificial timelike outer boundaries in numerical studies of test fields based on a 3+1 decomposition of asym…
Hyperboloidal foliations with scri-fixing in spherical symmetry
Anil Zenginoglu, Sascha Husa
We study in spherical symmetry the conformal compactification for hyperboloidal foliations with nonvanishing constant mean curvature. The conformal factor and the coordinates are c…
