Evolutions of unequal mass, highly spinning black hole binaries

We evolve a binary black hole system bearing a mass ratio of q = m(1)/m(2) = 2/3 and individual spins of S-1(z)/m(1)(2) = 0.95 and S-2(z)/m(2)(2) = -0.95 in a configuration where the large black hole has its spin antialigned with the orbital angular momentum, L-z, and the small black hole has its spin aligned with L-z. This configuration was chosen to measure the maximum recoil of the remnant black hole for nonprecessing binaries. We find that the remnant black hole recoils at just above 500 km/s, the largest recorded value from numerical simulations for aligned spin configurations. The remnant mass, spin, and gravitational waveform peak luminosity and frequency also provide a valuable point in parameter space for source modeling.
