Preface

This is a 6 lecture series on weak gravitational lensing presented at the inaugral school of the Indian Association for General Relativity and Gravitation held in May 2022.

Tutorials/Assignments

There will be 4 tutorials conducted in conjunction with the series of lectures. The tutorials will help you to write python code to measure the weak lensing signal around a collection of galaxy clusters.

Lecture notes:

I will try to maintain lecture notes as python notebooks, but these notes will heavily borrow from the texts above. Therefore, there will be quite some overlap between the notes and some of these texts. Authoratative versions will always be found in the above texts. I will also use codes which will use functions from different publicly available python packages like numpy, scipy, matplotlib, sympy.

Purpose of the lecture notes

The lecture notes are an evolving document and will aid as reference material. I will try to keep it updated via github (open github accounts if you do not already have them) and add all of the members as collaborators. If you find interesting things you would like to add to these lecture notes, then please fork the project and send pull requests to me.
