This repository contains the JUPYTER notebooks that accompany the textbook Dark Matter by David J. E. Marsh, David Ellis, and Viraf M. Mehta. These notebooks can be used to reproduce certain figures and numerical exercises from the textbook.

Contents

These notebooks will be continually updated. An outline of the current content is as follows:

• Rotation Curves - (Chapter 3). Plot a simple galaxy rotation curve, and fit different dark matter profiles to data.
• Gravitational Lensing - (Chapter 4). A simplified exercise to compute the ellipticity of regions in a sample image, and lens this image.
• WIMP Relic Density - (Chapter 9). Numerically solve the Boltzmann equation and hence produce figures for Y(T).
• Axion Relic Density - (Chapter 10). Numerically solve the Klein-Gordon equation and hence produce figures for Φ(t).
• WIMP Direct Detection - (Chapter 10). Compute recoils rates and exclusion limits.
• Axion Direct Detection - (Chapters 14 and 15). Estimate exclusions from haloscopes, helioscopes, and horizontal branch stars.
• PBH Microlensing - (Chapter 16). Compute the rate and number of microlensing events, and thus a simple exclusion.

Notes for Lecturers

If you are using these exercises as part of a course you are teaching, please feel free to clone this repository or download it as a zip file. The solutions can then be hidden in your local version.
