Parameter matching between horizon quasi-local and point-particle definitions at 1PN for quasi-circular and non spinning BBH systems in harmonic gauge
Dongze Sun, Leo C. Stein
We investigate how commonly used parameter definitions in Post-Newtonian (PN) theory compare with those from Numerical Relativity (NR) for binary black hole (BBH) systems. In NR, m…
Gauge Boundary conditions to mitigate center-of-mass drift in BBH simulations
Dongze Sun, Sizheng Ma, Mark A. Scheel +1
Long-term numerical relativity (NR) simulations of binary black hole (BBH) systems in the Spectral Einstein Code (SpEC) code exhibit an unexpected exponential drift of the center-o…
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…
Modeling the BMS transformation induced by a binary black hole merger
Guido Da Re, Keefe Mitman, Leo C. Stein +12
Understanding the characteristics of the remnant black hole formed in a binary black hole merger is crucial for conducting gravitational wave astronomy. Typically, models of remnan…
