Deterministic reproducibility capsule for GIFT Paper 1. Reproduces the deep-regime scaling and normalization of the RAR and BTFR from the SPARC dataset using fixed-slope ODR fits. Code, derived data, and verification figures included. Archived snapshot: Zenodo DOI 10.5281/zenodo.18513729.

Code and data for analyzing action coherence in a galactic simulation, as part of the paper of 'Evolution of action-space coherence in a MIlky Way-like simulation' by Arunima et al

Repository for hosting MHD codes for Galatic Dynamo simulations.

The ACM Trunk: a rigid holographic framework for galactic dynamics. This repository provides the core analytical engine for predicting galaxy rotation behavior from baryonic distributions via linear holographic screening. Tagline No galaxy-by-galaxy fits. No hidden knobs. Just the physics of the background floor.

Planet 9 disproved by Galactic Dominance Beyond Solar Gravitational Boundary

All 8 Virgo galaxies show DECLINING rotation curves. All 10 field galaxies show FLAT rotation curves. This is exactly what MOND/Entropic Gravity predicts.

Wide binary stars at large separations show 27.7% higher orbital velocities than Newtonian prediction — exactly as MOND predicts.

Covariance-aware BIC sensitivity implementation stopped when the frozen diagonal galaxy fit failed deterministic reproduction.

Burkert-backbone + BIC-selected Gaussian shells fit to 102 SPARC rotation curves (T=2–9). Companion code and data for Bibb (2026).
