The trumpet solution from spherical gravitational collapse with puncture gauges
Marcus Thierfelder, Sebastiano Bernuzzi, David Hilditch +2
We investigate the stationary end-state obtained by evolving a collapsing spherical star with the gauges routinely adopted to study puncture black holes. We compare the end-state o…
Stability of the puncture method with a generalized BSSN formulation
Helvi Witek, David Hilditch, Ulrich Sperhake
The puncture method for dealing with black holes in the numerical simulation of vacuum spacetimes is remarkably successful when combined with the BSSN formulation of the Einstein e…
Constraint preserving boundary conditions for the Z4c formulation of general relativity
Milton Ruiz, David Hilditch, Sebastiano Bernuzzi
We discuss high order absorbing constraint preserving boundary conditions for the Z4c formulation of general relativity coupled to the moving puncture family of gauges. We are prim…
Hyperbolic formulations of General Relativity with Hamiltonian structure
David Hilditch, Ronny Richter
With the aim of deriving symmetric hyperbolic free-evolution systems for GR that possess Hamiltonian structure and allow for the popular puncture gauge condition we analyze the hyp…
