已经证实，高维旋转黑洞在足够大的旋转值时变得不稳定，并且在不稳定性的阈值处出现具有收缩视界的新黑洞。我们搜索数值，并找到一个单一的旋转，标志着发病的不稳定性和新的黑洞阶段的出现的迈尔斯-佩里黑洞的静态轴对称扰动。我们还发现了新的超自旋格雷戈里-拉弗拉姆不稳定性的旋转黑弦和膜。
It has been conjectured that higher-dimensional rotating black holes become unstable at a sufficiently large value of the rotation, and that new black holes with pinched horizons appear at the threshold of the instability. We search numerically and find the stationary axisymmetric perturbations of Myers-Perry black holes with a single spin that mark the onset of the instability and the appearance of the new black hole phases. We also find new ultraspinning Gregory-Laflamme instabilities of rotating black strings and branes.
