标题： Ultimate Black Hole Recoil: What the maximum high energy collisions kick is?

摘要： 我们进行了一系列1381次高能黑洞碰撞的全数值模拟，以寻找它们合并后的最大反冲速度。 我们考虑质量相等的双星系统，其自旋方向沿轨道平面相反，并对自旋取向、碰撞参数和初始动量进行搜索，以找到给定自旋幅度$s$的最大反冲速度。 此自旋序列对于$s=0.4, 0.7, 0.8, 0.85, 0.9$是外推到极端情况$s=1$，以获得估计的最大反冲速度为$28,562\pm 342$km/s，因此大约被限制为$10\%$倍光速。 显示英文摘要

摘要： We performed a series of 1381 full numerical simulations of high energy collision of black holes to search for the maximum recoil velocity after their merger. We consider equal mass binaries with opposite spins pointing along their orbital plane and perform a search of spin orientations, impact parameters, and initial linear momenta to find the maximum recoil for a given spin magnitude $s$. This spin sequence for $s=0.4, 0.7, 0.8, 0.85, 0.9$ is then extrapolated to the extreme case, $s=1$, to obtain an estimated maximum recoil velocity of $28,562\pm 342$ km/s, thus approximately bounded by $10\%$ the speed of light.
