Recent numerical relativistic results demonstrate that the merger of comparable-mass spinning black holes has a maximum “recoil kick” of up to ~4000 km s−1. However, the scaling of these recoil velocities with mass ratio is poorly understood. We present new runs showing that the maximum possible kick perpendicular to the orbital plane does not scale as ~η2 (where η is the symmetric mass ratio), as previously proposed, but is more consistent with ~η3, at least for systems with low orbital precession. We discuss the effect of this dependence on galactic ejection scenarios and retention of intermediate-mass black holes in globular clusters.

Journey to the MBH-σ relation: the fate of low-mass black holes in the Universe (2009, methodology): “We include the effects of gravitational recoil by adopting the fitting formula proposed by Lousto & Zlochower (2009; see also Baker et al. 2008).”
Doing Science with eLISA: Astrophysics and Cosmology in the Millihertz Regime (2012, background): “When coalescence occurs, the merger remnant “recoils”because of the anisotropic emission of gravitational waves (Baker et al., 2008), moving away from the gravitational centre of the galaxy.”
The evolution of massive black holes and their spins in their galactic hosts (2012, background): “It seems, however, that this discrepancy originated because Lousto & Zlochower (2009) and Baker et al. (2008) considered two different regions of the parameter space.”
A LARGE SYSTEMATIC SEARCH FOR CLOSE SUPERMASSIVE BINARY AND RAPIDLY RECOILING BLACK HOLES (2011, unknown): “However, under most other configurations, the recoil speed is considerably lower than this value (e.g., Campanelli et al. 2007a,b; Baker et al. 2008).”
Black-hole binaries, gravitational waves, and numerical relativity (2010, methodology): “Studies of various model-dependent speed probabilities are given by Schnittman (2007) and Baker et al. (2008a).”
THE ASSEMBLY OF SUPERMASSIVE BLACK HOLES AT HIGH REDSHIFTS (2008, methodology): “We use the mean values given in Baker et al. (2008) for the fitting parameters: A = 1.35 × 104 km s−1, B = −1.48, H = 7540 km s−1, 3 Note that this notation differs slightly from Baker et al. (2008)—we have simplified their notation to be more transparent in our spherically symmetric geometry.”
