Symmetric gravitational closure
Maximilian Düll, Nils L. Fischer, Bjoern Malte Schaefer +1
We show how to exploit symmetry assumptions to determine the dynamical equations for the particular geometry that underpins given matter field equations. The procedure builds on th…

A hp-adaptive discontinuous Galerkin solver for elliptic equations in numerical relativity
Trevor Vincent, Harald P. Pfeiffer, Nils L. Fischer
A considerable amount of attention has been given to discontinuous Galerkin methods for hyperbolic problems in numerical relativity, showing potential advantages of the methods in…

The SXS Collaboration catalog of binary black hole simulations
Michael Boyle, Daniel Hemberger, Dante A. B. Iozzo +37
Accurate models of gravitational waves from merging black holes are necessary for detectors to observe as many events as possible while extracting the maximum science. Near the tim…
