| Résumé≠ | 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. | Galaxy rotation curve analysis is the technique of measuring how orbital velocities change with distance from the center of a galaxy. Pioneered by Vera Rubin and W. Kent Ford Jr. in 1970, rotation curves revealed one of astronomy's great mysteries: galaxies rotate too fast to be held together by their visible stars alone, providing direct evidence for dark matter. |
