Strongly gravitating systems, such as black holes, serve as natural setups to test the validity of our current theory of gravity - Einstein's theory of general relativity (GR). Identifying any deviations from GR will radically enhance our fundamental knowledge about the structure of space-time, gravity and quantum mechanics. This project aims to reveal unknown structure of GR in the strong field regime and quantum aspects of black holes. Using both conventional analytical methods and innovative techniques imported from high energy physics, new insights on the physically relevant solutions will be reached. These findings will be important to resolve the exact shadows of binary black holes, gain insights in black hole jets purely in terms of a gravity-free quantum field theory and restore quantum information in black holes. The outreach plan of this project will create new opportunities for professional development for graduate and undergraduate students and address the needs of the local elementary schools lacking solid science programs.More precisely, the research objectives of this proposal are the following. First, construct efficient computational methods for imaging (including movies) the exact shadows for extremal, un-equal mass or eccentric binary black holes applying the so-called quasi-static methods. Second, establish a new holographic duality for the Blandford-Znajek mechanism of energy extraction from rotating black holes. Last, provide a robust methodology to explain how the physical information falling into a BH in GR is encrypted in its event horizon.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

强引力系统，例如黑洞，可以作为测试当前引力理论（爱因斯坦广义相对论（GR））有效性的自然设置。识别与广义相对论的任何偏差将从根本上增强我们关于时空结构、引力和量子力学的基础知识。该项目旨在揭示黑洞强场状态和量子方面未知的广义相对论结构。使用传统的分析方法和从高能物理学引入的创新技术，将获得对物理相关解决方案的新见解。这些发现对于解决双黑洞的精确阴影、纯粹根据无重力量子场论获得黑洞喷流的见解以及恢复黑洞中的量子信息非常重要。该项目的推广计划将为研究生和本科生的专业发展创造新的机会，并解决当地缺乏扎实科学课程的小学的需求。更准确地说，该提案的研究目标如下。首先，构建有效的计算方法，应用所谓的准静态方法对极值、不等质量或偏心双黑洞的精确阴影进行成像（包括电影）。其次，为从旋转黑洞提取能量的 Blandford-Znajek 机制建立新的全息对偶性。最后，提供一种稳健的方法来解释落入 GR 中的 BH 的物理信息如何在其事件视界中进行加密。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
