Finding black hole spins efficiently during a numerical binary evolution
Himanshu Chaudhary, Rob Owen, Mark A. Scheel +1
The dynamics of a binary black hole system depend on its masses and spins. For a binary at finite separation, it is not possible to define these quantities in an unambiguous way; h…

Parameter control for binary black hole initial data
Iago B. Mendes, Nils L. Vu, Oliver Long +2
When numerically solving Einstein's equations for binary black holes (BBH), we must find initial data on a three-dimensional spatial slice by solving constraint equations. The cons…

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…
