引力微透镜简介

Introduction to Gravitational Microlensing

Shude Mao

摘要:

介绍了引力微透镜的基本概念。我们从透镜方程开始,然后推导出像的位置和放大率。然后描述光学深度和事件率的统计量。最后,我们总结了一份挑战和开放性问题的清单。给学生一套练习题。

英文摘要:

The basic concepts of gravitational microlensing are introduced. We start with the lens equation, and then derive the image positions and magnifications. The statistical quantities of optical depth and event rate are then described. We finish with a summary and a list of challenges and open questions. A problem set is given for students to practice.
