A Unified Empirical Timescale for Galaxy Dynamics from Kinematic Scale Competition

Abstract We define a unified, empirically constructed dynamical observable τ, expressed as a signed characteristic timescale (in Myr), derived from two structural scales extracted directly from kinematic data: a dynamical coherence length ξ_GL and a baryonic confinement scale r_core.
