Below you'll find links to a collection of tutorials which show you how to perform simple calculations with Galacticus. The parameter files needed for each tutorial can be found in the parameters/tutorials/ folder of the Galacticus source distribution.

Note that the later tutorials build on the ideas presented in the earlier ones, so it's recommended to work through them in order.

Introductory tutorials

• Introduction to Galacticus parameter files

Dark matter halo related tutorials

• Computing the halo mass function
• Computing dark matter only merger trees
• Computing the warm dark matter halo mass function
• Solving the excursion set problem

Working with stellar populations

• Instantaneous & Non-instantaneous recycling
• Postprocessing of stellar spectra

Working with N-body Merger Trees

• Using N-body Merger Trees
• Generating Mock Catalogs with Lightcones

Miscellaneous

• Computing power spectra
• Computing the warm dark matter power spectra
• Reionization calculations
• Constraining Galacticus parameters
• Extracting star formation histories

Interactive tutorials

These are typically Jupyter notebook-based interactive examples of how to work with Galacticus data:

• Basics of Galacticus and galaxy formation (aimed at advanced high school students / beginning undergrads; created by Charles Gannon)
