引力透镜解析研究综述

A review on analytical studies in Gravitational Lensing

Abhishek Chowdhuri, Saptaswa Ghosh, Arpan Bhattacharyya

AI总结:

本文综述了广义相对论框架下黑洞引力透镜的解析研究,涵盖史瓦西时空、Kerr度规及black-bounce时空,并探讨利用天体物理和宇宙学数据约束相关参数。

摘要:

在本研究中,我们回顾了当前关于黑洞引力透镜的一些研究,主要是在广义相对论框架下进行的。我们主要关注与透镜效应相关的解析研究,并参考观测结果。我们首先回顾球对称史瓦西时空中的透镜效应,展示如何计算偏转角,然后转向旋转对应体——Kerr度规。此外,我们将研究扩展到一类新提出的特殊解,称为black-bounce时空,并在整个综述中讨论如何在这些时空中探索透镜效应,以及如何利用现有的天体物理和宇宙学数据对各种参数进行约束。

英文摘要:

In this study, we review some current studies on Gravitational Lensing for black holes, mainly in the context of general relativity. We mainly focus on the analytical studies related to lensing with references to observational results. We start with reviewing lensing in spherically symmetric Schwarzschild spacetime, showing how to calculate deflection angles before moving to the rotating counterpart, the Kerr metric. Furthermore, we extend our studies for a particular class of newly proposed solutions called black-bounce spacetimes and discuss throughout the review how to explore lensing in these spacetimes and how the various parameters can be constrained using available astrophysical and cosmological data.
