引力透镜的严格方法

Rigorous Approach to the Gravitational Lensing

Minjoon Park

摘要:

通过构造一个尽可能精确地描述实际系统的装置并求解零测地线方程,我们重新讨论了弱引力透镜问题。给出了仅由宇宙学常数Λ驱动的宇宙的详细情况,这证实了传统的结果:传统的透镜分析是正确的,不需要任何校正O(Λ)。我们还处理的情况下,在通用FRW背景的透镜。

英文摘要:

We revisit a weak gravitational lensing problem by constructing a setup which describes the actual system as accurately as possible and solving the null geodesic equations. Details are given for the case of a Universe driven only by a cosmological constant, Λ, which confirm the conventional results: The conventional lensing analysis is correct as it is, without any need for correction of O(Λ). We also treat the cases of the lensing in generic FRW backgrounds.
