The following are a collection of useful reference works (papers, presentations, classes, etc.) the describe the astrophysics which Galacticus incorporates. These are primarily reference and introductory works.

Cosmology

• "Introduction to Cosmology" - Barbara Ryden's upper-level undergrad textbook - a nice introduction to the basics of cosmology

Linear growth of structure

• Chapter 3 of Tom Theuns' course notes on physical cosmology has a detailed derivation of the growth of small perturbations in an expanding universe

Power spectra

• Chapter 3 of Tom Theuns' course notes on physical cosmology explains how the power spectrum is defined and computed

Nonlinear collapse

• Chapter 4 of Tom Theuns' course notes on physical cosmology derives solutions for spherical collapse of nonlinear perturbations

Dark matter

• A Primer on Dark Matter In this article we review the basic evidence for dark matter and the role it plays in cosmology and astrophysics, and discuss experimental searches and potential candidates. Rather than targeting researchers in the field, we aim to provide an accessible and concise summary of the most important ideas and results, which can serve as a first entry point for advanced undergraduate students of physics or astronomy.

Dark matter halos and Merger trees

• Lecture 10 of Frank van den Bosch's class "Theory of galaxy formation" explains dark matter halos, the derivation of the Press-Schechter mass function, and has a simple overview of how this is used to construct merger trees
