标题： Inspiral into Gargantua

摘要： 我们模拟一个致密天体旋进到一个质量更大且非常接近理论最大旋转速度的黑洞。 我们发现，一旦该天体进入近视界区域，引力辐射的特点是频率恒定，等于（两倍）视界频率，且具有指数衰减的波形。 这与通常的“啁啾”行为形成对比，如果被探测到，将构成自然界中近极端黑洞的“确凿证据”。 显示英文摘要

摘要： We model the inspiral of a compact object into a more massive black hole rotating very near the theoretical maximum. We find that once the body enters the near-horizon regime the gravitational radiation is characterized by a constant frequency, equal to (twice) the horizon frequency, with an exponentially damped profile. This contrasts with the usual "chirping" behavior and, if detected, would constitute a "smoking gun" for a near-extremal black hole in nature.
