Modeling maximum astrophysical gravitational recoil velocities

Lousto, Carlos O., Zlochower, Yosef

Understand

We measure the recoil velocity as a function of spin for equal-mass, highly-spinning black-hole binaries, with spins in the orbital plane, equal in magnitude and opposite in direction.

  • We confirm that the leading-order effect is linear in the spin and the cosine of angle between the spin direction and the infall direction at merger.
  • We find higher-order corrections that are proportional to the odd powers in both the spin and cosine of this angle.
  • Taking these corrections into account, we predict that the maximum recoil will be 3680+-130 km/s.
