额外维度时空中的引力透镜效应

中文摘要 AI 辅助

这是本系列论文的第四篇，在该系列中我们考虑利用宇宙学额外维度来解释宇宙的加速膨胀和旋涡星系的旋转曲线，而无需引入暗物质和暗能量。在此，我们研究这一设定下的引力透镜效应；我们推导了时间延迟的表达式，并提出了一种修正的质量重建过程似然函数，该函数考虑了额外维度膨胀或收缩的影响。

英文摘要

This is the fourth paper of a series in which we consider the possibility to use cosmological extra dimensions to explain the accelerated expansion of the Universe and the rotation curve of spiral galaxies without introducing dark matter and dark energy. Here we study gravitational lensing in this setting; we derive an expression for time delay and present a modified likelihood for the mass reconstruction procedure which takes into account the effect of the expansion or contraction of the extra dimensions.
