Horizon Boundary Condition for Black Hole Spacetimes
Peter Anninos, Greg Daues, Joan Masso +2
It was recently shown that spacetime singularities in numerical relativity could be avoided by excising a region inside the apparent horizon in numerical evolutions. In this paper…
Formation gf Bosonic Compact Objects
Edward Seidel, Wai-Mo Suen
We showed that compact bosonic objects can be formed through a process we called gravitational cooling. A central issue in the subject of boson star is whether a classical field co…
Invariant Algebraic Slicing of the Spacetime
Carles Bona, Joan Stela, Joan Masso +1
Using the momentum constraint, the standard evolution system is written in a fully first order form. The class of first order invariant algebraic slicing conditions is considered.…
3D Numerical Relativity at NCSA
Peter Anninos, Karen Camarda, Joan Masso +4
Numerical relativity is finally coming of age with the development of massively parallel computers. 3D problems, which were completely intractable several years ago due to limited…
A 3D Apparent Horizon Finder
Joseph Libson, Joan Masso, Edward Seidel +1
We report on an efficient method for locating the apparent horizon in numerically constructed dynamical 3D black hole spacetimes. Instead of solving the zero expansion partial diff…
Adaptative Mesh Refinement in Numerical Relativity
Joan Masso, Edward Seidel, Paul Walker
We discuss the use of Adaptative Mesh Refinement (AMR) techniques in dynamical black hole spacetimes. We compare results between traditional fixed grid methods and a new AMR applic…
