利用电磁波和引力波进行强场重力试验

Strong field tests of gravity with electromagnetic and gravitational waves

Sourabh Nampalliwar

摘要:

近一个世纪以来,爱因斯坦的引力理论一直是描述宇宙引力现象的标准理论。随着它的成功,从理论上的理论的局限性(例如,奇点)和观测(例如,暗物质/能量)的观点已经出现。这导致了修改或取代爱因斯坦理论的建议,并根据数据测试这些理论,特别是在强场制度中,近年来已成为物理学的新范式。随着引力波这一全新的研究途径的出现,基于电磁波的新的、改进的技术也被越来越严格地用于检验广义相对论。由于超越GR的领域是未知的,一个流行的方法是寻找与GR/GR预测的理论不可知的偏差。在这里,我描述了我如何使用引力波,X射线和黑洞阴影来限制这些理论不可知的偏差。

英文摘要:

For nearly a century, Einstein's theory of gravity has been the standard theory for describing gravitational phenomena in our universe. Along with its successes, limitations of the theory from theoretical (e.g., singularities) and observational (e.g., dark matter/energy) perspectives have appeared. This has led to proposals that modify or supersede Einstein's theory, and testing these theories against data, especially in the strong-field regime, has emerged as a new paradigm in physics in recent years. Along with the completely new avenue of gravitational waves, new and improved techniques based on electromagnetic waves are being used to test general relativity (GR) ever more stringently. As the realm beyond GR is unknown, a popular approach is to look for theory-agnostic deviations from GR/predictions of GR. Here I describe how I have used gravitational waves, X-rays, and black hole shadows to put constraints on some of these theory-agnostic deviations.
