Modeling Gravitational Recoil Using Numerical Relativity

Understand

We review the developments in modeling gravitational recoil from merging black-hole binaries and introduce a new set of 20 simulations to test our previously proposed empirical formula for the recoil.

• The configurations are chosen to represent generic binaries with unequal masses and precessing spins.
• Results of these simulations indicate that the recoil formula is accurate to within a few km/s in the similar mass-ratio regime for the out-of-plane recoil.
