Convergence of post-Newtonian for quasi-circular non-precessing comparable mass ratios BBHs
Dongze Sun, Béatrice Bonga, Leo C. Stein +1
Post-Newtonian (PN) theory provides the analytic foundation for modeling the early inspiral of binary black holes. However, as an asymptotic series, successive PN orders do not nec…
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…
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…
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…
