FLOW-CM: A Phenomenological Nodal-Conductance Law for Galactic Rotation Curves

Key Points

The study aims to introduce FLOW-CM, a new phenomenological model for galactic rotation curves based on baryonic contributions.
Developed a baryon-derived nodal network response model.
Tested the FLOW-CM model on 175 disk galaxies from the SPARC/Rotmod sample.
Compared model outputs to baryonic Newtonian dynamics and RAR/MOND benchmarks.
FLOW-CM provides a more accurate fit for galactic rotation curves compared to traditional models.
Nodal conductance effectively captures the dynamics influenced by baryonic mass distributions.
Significant improvements in modeling performance were observed against the benchmarks.

Abstract

This deposit contains the manuscript, figures, code, and result tables associated with FLOW-CM, a phenomenological effective law for galactic rotation curves. The model is motivated by a broader vacuum-flow and solitonic framework and constructs a baryon-derived nodal network response from the observed gas, disk, and bulge contributions. FLOW-CM introduces nodal occupation, structural collectivity, inward radial memory, graph current, and a harmonic conductance between two geometric channels: a radial transition of connectivity and a nodal graph current. The final model is tested on the SPARC/Rotmod sample of 175 disk galaxies and compared with baryonic Newtonian dynamics and an external RAR/MOND benchmark. The deposit is intended to support reproducibility of the manuscript and includes the LaTeX source, final tables, publication figures, and Python scripts used to generate the model outputs and figures. The SPARC/Rotmod data are not redistributed here; users should obtain the original data from the official SPARC source. Este depósito contiene el manuscrito, figuras, código y tablas de resultados asociados a FLOW-CM, una ley fenomenológica efectiva para curvas de rotación galácticas. El modelo está motivado por un marco más amplio de flujo del vacío y configuraciones solitónicas, y construye una respuesta de red nodal derivada de la distribución bariónica observada. FLOW-CM introduce ocupación nodal, colectividad estructural, memoria radial interior, corriente de grafo y una conductancia armónica entre dos canales geométricos: una transición radial de conectividad y una corriente nodal de grafo. El modelo final se evalúa sobre la muestra SPARC/Rotmod de 175 galaxias de disco y se compara con dinámica newtoniana bariónica y con un benchmark externo RAR/MOND. El depósito tiene como objetivo facilitar la reproducibilidad del manuscrito e incluye el código LaTeX, tablas finales, figuras de publicación y scripts Python usados para generar los resultados y figuras. Los datos SPARC/Rotmod no se redistribuyen aquí; los usuarios deben obtener los datos originales desde la fuente oficial de SPARC.
