Baryonic acceleration closure across gas-rich dwarfs, disk galaxies, and galaxy clusters

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}\rightarrow10^{-10}\rightarrow10^{-9},{\rm m,s^{-2}}) can be organized through baryonic geometry, effective participation, and confinement, rather than by imposing a single universal acceleration scale.
