UDCT v5.2: Enhanced Comparison Framework and Redshift-Dependent Analysis Strategy for Galaxy Rotation Curves

This repository contains the official standalone reproducibility package for UDCT v5.2, including the User Manual, Python implementation, and README. It provides a dedicated --compare mode for efficient Static vs Dynamic model comparison on galaxy rotation curves using the Dynamic Self-Regulating Bidirectional Back-Reaction (DSBB) model. v5.2 introduces a redshift-binned analysis strategy to help identify the influence of FLRW cosmological assumptions at higher redshifts. The package is designed as a practical tool for current datasets (such as SPARC) and as a foundation for future sovereign empirical verification approaches. When large-scale datasets from upcoming telescopes such as Rubin/LSST, Euclid, and Roman become publicly available, this package will enable verification in FLRW-free or near-FLRW-free mode across redshift bins using released data containing tens of thousands of data points. The new Compare mode also allows researchers to quickly compare and validate results across multiple galaxies directly on a laptop.
