Chapter 1: Strong Lensing

In chapter 1, we introduce you to strong gravitational lensing and the core PyAutoLens API.

Colab links to every tutorial are included.

The chapter contains the following tutorials:

Tutorial 0: Visualization - Setting up PyAutoLens’s visualization library.

Tutorial 1: Grids And Galaxies - Using grids of (y,x) coordinates with galaxies made up of light profiles.

Tutorial 2: Ray Tracing - Using grids, galaxies and mass profiles to perform strong lens ray-tracing.

Tutorial 3: More Ray Tracing - Advanced strong lens ray-tracing.

Tutorial 4: Point Sources - How lensing calculations when the source galaxy is a point-source (e.g. a quasar).

Tutorial 5: Lensing Formalism - The algebraic lensing formalism used to describe strong lensing.

Tutorial 6: Data - Loading and inspecting telescope imaging data of a strong lens.

Tutorial 7: Fitting - Fitting data with a strong lens model.

Tutorial 8: Summary - A summary of the chapter.
