AI 中文摘要
我们研究了极强电磁辐射脉冲直至引力坍缩及之后的引力相互作用。我们证明了对于单个脉冲以及此类脉冲的正面碰撞，存在接近坍缩阈值的非常致密的状态，并且测量到它们的致密性高于箍猜想提出的最大值。对于高于坍缩阈值的单个脉冲，会产生一个快速黑洞。根据调节量的不同，正面碰撞可形成两个无视界状态、两个小黑洞或一个大黑洞。我们的结果表明，无质量场的引力相互作用可导致非平凡的最终或中间状态，同时产生极高的光度和致密性。
英文摘要
We study the gravitational interaction of very strong pulses of electromagnetic radiation, up to and beyond gravitational collapse. We demonstrate the existence of very compact states close to the threshold of collapse, both for a single pulse, and a head-on collision of such pulses, and we measure their compactness to be above the maximum value proposed by the hoop conjecture. For a single pulse above the threshold of collapse, a fast black hole is produced. Depending on the amount of tuning, head-on collisions can form two horizonless states, two small black holes or one big black hole. Our results show that the gravitational interaction of massless fields can lead to nontrivial final or intermediate states, while giving rise to extremely high luminosity and compactness.
