Surrogate models for precessing binary black hole simulations with unequal masses

Davide Gerosa, Harald P. Pfeiffer, Jonathan Blackman, Lawrence E. Kidder, Leo C. Stein, Mark A. Scheel, Scott E. Field, Vijay Varma

New surrogate models NRSur7dq4 and RemnantModel accurately predict waveforms and remnant properties for precessing unequal-mass binary black holes up to q=4, outperforming existing models by an order of magnitude.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

In their training parameter range, both models are shown to be more accurate than existing models by at least an order of magnitude, with errors comparable to the estimated errors in the numerical relativity simulations.

C2weakest assumption

The 1528 numerical relativity simulations with q ≤ 4 and χ ≤ 0.8 sufficiently sample the parameter space so that the surrogate fitting generalizes without significant overfitting or missing physics.
