In search of the maximum lost momentum

We performed a series of 1381 full numerical simulations of high energy collision of two black holes to search for the maximum recoil velocity after their merger. We studied equal mass binaries with opposite spins pointing along the orbital plane to maximize asymmetric gravitational radiation and performed a search of spin orientations in the plane, impact parameters, and initial linear momenta to find a maximum recoil velocity extrapolated to the extreme spinning case of 28, 562 & PLUSMN; 342km/s, thus tightly bounding recoil by 10% the speed of light.
