Choptuik scaling in six dimensions
David Garfinkle, Curt Cutler, G. Comer Duncan
We perform numerical simulations of the critical gravitational collapse of a spherically symmetric scalar field in 6 dimensions. The critical solution has discrete self-similarity.…
Symmetry-seeking spacetime coordinates
D. Garfinkle, C. Gundlach
In numerically constructing a spacetime that has an approximate timelike Killing vector, it is useful to choose spacetime coordinates adapted to the symmetry, so that the metric an…
Null infinity and an electromagnetic analog of the relativistic Kepler problem
David Garfinkle
This paper has been withdrawn by the author. It has come to my attention that most of the results reported here have already been obtained by Ludvigsen.
Numerical simulations of Gowdy spacetimes on S2XS1XR
David Garfinkle
Numerical simulations are performed of the approach to the singularity in Gowdy spacetimes on S2XS1XR. The behavior is similar to that of Gowdy spacetimes on T3XR. In particular, t…
Metrics with distributional curvature
David Garfinkle
This paper considers metrics whose curvature tensor makes sense as a distribution. A class of such metrics, the regular metrics, was defined and studied by Geroch and Traschen. Her…
