Halo Occupation Distribution
Halo Occupation Distribution (HOD) modeling is a framework for relating observed galaxy clustering to the distribution of galaxies within dark matter halos. Developed by Jia Peacock and others around 2000, HOD provides a flexible, physically motivated approach to interpreting galaxy surveys and understanding how galaxies populate dark matter halos across cosmic time.
