Are moving punctures equivalent to moving black holes?
When simulating the inspiral and coalescence of a binary black-hole system, special care needs to be taken in handling the singularities. Two main techniques are used in numerical-relativity simulations: A first and more traditional one “excises” a spatial neighbourhood of the singularity from the numerical grid on each spacelike hypersurface. A second and more recent one, instead, begins with ...

متن کاملMoving black holes in 3D
We model a radiating, moving black hole in terms of a worldtube–null-cone boundary value problem. We evolve this data in the region interior to the worldtube, but exterior to a trapped surface by means of a characteristic evolution based upon a family of ingoing null hypersurfaces. Data on the worldtube is induced from a Schwarzschild spacetime, but the worldtube is allowed to move relative to ...
متن کاملNumerical black holes: A moving grid approach.
Spherically symmetric (1D) black-hole spacetimes are considered as a test for numerical relativity. A finite difference code, based in the hyperbolic structure of Einstein’s equations with the harmonic slicing condition is presented. Significant errors in the mass function are shown to arise from the steep gradient zone behind the black hole horizon, which challenge the Computational Fluid Dyna...
متن کامل6 Where do moving punctures go ?
Currently the most popular method to evolve black-hole binaries is the “moving puncture” method. It has recently been shown that when puncture initial data for a Schwarzschild black hole are evolved using this method, the numerical slices quickly lose contact with the second asymptotically flat end, and end instead on a cylinder of finite Schwarzschild coordinate radius. These slices are statio...
