Strong Field Scattering of Black Holes: Assessing Resummation Strategies

Understand

Recent developments in post-Minkowksian (PM) calculations have led to a fast-growing body of weak-field perturbative information.

• As such, there is major interest within the gravitational wave community as to how this information can be used to improve the accuracy of theoretical waveform models.
• In this work, we build on recent efforts to validate high-order PM calculations using numerical relativity simulations.
• We present a new set of high-energy scattering simulations for equal-mass, non-spinning binary black holes, further expanding the existing suite of NR simulations.
