标题： A slightly less grand challenge: Colliding Black Holes using perturbation techniques

摘要： 扰动技术可以作为超级计算机计算的替代方法，用于计算由碰撞黑洞发射的引力辐射，前提是该过程以黑洞彼此靠近开始。 我们概述了该方法，并给出了针对各种初始配置（轴对称和无对称）所得的结果：最初静止的、相互接近的、反向旋转的或以一定角度被加速（伪螺旋运动）的。 在适用的情况下，我们将扰动结果与超级计算机计算进行了比较。 显示英文摘要

摘要： Perturbation techniques can be used as an alternative to supercomputer calculations in calculating gravitational radiation emitted by colliding black holes, provided the process starts with the black holes close to each other. We give a summary of the method and of the results obtained for various initial configurations, both axisymmetric and without symmetry: Initially static, boosted towards each other, counter-rotating, or boosted at an angle (pseudo-inspiral). Where applicable, we compare the perturbation results with supercomputer calculations.
