Probing the ringdown perturbation in binary black hole coalescences with an improved quasi-normal mode extraction algorithm
Keefe Mitman, Isabella Pretto, Harrison Siegel +9
Using gravitational waves to probe the geometry of the ringing remnant black hole formed in a binary black hole coalescence is a well-established way to test Einstein's theory of g…

The SXS Collaboration's third catalog of binary black hole simulations
Mark A. Scheel, Michael Boyle, Keefe Mitman +56
We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration's catalog of binary black hole simulations. Using highly efficient spectral methods implemented i…

Automated determination of the end time of junk radiation in binary black hole simulations
Isabella G. Pretto, Mark A. Scheel, Saul A. Teukolsky
When numerically solving Einstein's equations for the evolution of binary black holes, physical imperfections in the initial data manifest as a transient, high-frequency pulse of '…
