Baryonic Acceleration Closure Across Gas-Rich Dwarfs, Disk Galaxies, and Galaxy Clusters

Authors: Federico Quinteros

This manuscript proposes a common baryonic closure for the radial acceleration relation in gas-rich dwarf galaxies, SPARC disks, and CLASH galaxy clusters. The same algebraic closure is retained across regimes, but the effective scale (a_U) is built from local baryonic physics: H I structure in disks, Toomre stability and pressure support in dwarfs, and baryon depletion plus hydrostatic—geometric confinement in clusters. The work shows how the hierarchy (10^{-11}ightarrow10^{-10}ightarrow10^{-9} {m m,s^{-2}}) can be organized through baryonic geometry, effective participation, and confinement, rather than by imposing a single universal acceleration scale.
