Evolutions of unequal mass, highly spinning black hole binaries

We evolve a binary black hole system bearing a mass ratio of $q=m_1\mathrm{/}{m}_2=2\mathrm{/}3$ and individual spins of $S_1^z\mathrm{/}{m}_1^2=0.95$ and $S_2^z\mathrm{/}{m}_2^2=-0.95$ 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 500km/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.
