Dendro-GR at high mass ratios with high spins
William K. Black, David W. Neilsen, Eric W. Hirschmann +1
The paper demonstrates that the Dendro-GR code can efficiently simulate binary black hole mergers with high mass ratios and high spins, producing accurate gravitational waveforms u…
Nonlinear Stability of Kerr-Sen Black Holes in Merging Binaries
Andrew Carroll, Eric W. Hirschmann, Hyun Lim +3
We investigate the stability of Kerr-Sen black holes, which arise in Einstein-Maxwell-dilaton-axion theory. Within a numerical relativity framework, we perform head-on binary black…
Nyquist-resolving gravitational waves via orbital frequency-based refinement
William K. Black, David Neilsen, Eric W. Hirschmann +2
Adaptive mesh refinement efficiently facilitates the computation of gravitational waveforms in numerical relativity. However, determining precisely when, where, and to what extent…
