A Unified Empirical Timescale for Galaxy Dynamics from Kinematic Scale Competition
Authors/Creators
Description
This record contains the manuscript and authoritative data products associated with “A Unified Empirical Timescale for Galaxy Dynamics from Kinematic Scale Competition.” The paper introduces a physically motivated dynamical timescale τ derived from the competition between coherence and confinement scales in galaxy kinematics, and demonstrates a strong empirical separation between rotation-supported and pressure-supported galaxies.
The release includes the full machine-readable data tables underlying all figures and statistical tests in the paper, together with analysis scripts used to generate the results. The datasets provided here constitute the authoritative versions referenced in the manuscript. Dataset can be found here; 10.5281/zenodo.17838463
