Scattering and dynamical capture of two black holes: synergies between numerical and analytical methods
Simone Albanesi, Alireza Rashti, Francesco Zappa +6
We study initially unbound systems of two black holes using numerical relativity (NR) simulations performed with GR-Athena++. We focus on regions of the parameter space close to th…
