Galaxy Clustering Tutorial ========================== This tutorial shows how to compute galaxy clustering statistics from halo properties using the Halo Occupation Distribution (HOD) framework. Learning Objectives ------------------- - Understand the halo model for galaxy clustering - Compute halo-halo correlation functions - Apply HOD models - Calculate observable galaxy clustering (:math:`\xi_{gg}(r)` and :math:`w_p(r_p)`) Overview -------- The halo model connects dark matter halos to observable galaxies through: 1. **Halo Mass Function**: :math:`\phi(M)` - abundance of halos 2. **Halo Clustering**: :math:`\xi_{hh}(r, M)` - spatial distribution 3. **HOD**: Occupation of galaxies within halos 4. **Galaxy Clustering**: :math:`\xi_{gg}(r)` - observable correlation function Coming soon: More detailed content for this tutorial.
