[Research 7] A Structural Interpretation of Galaxies

This study interprets galaxies as rotational systems that undergo structural differentiation and evolution governed by rotational stability and the conservation of angular momentum. During galaxy formation, matter does not accumulate indefinitely at the central region; rather, under conditions where the rotational velocity is maintained, it is radially redistributed to satisfy dynamical stability. As a result, galactic structure can be classified into a central region of localized rotational generation, a transitional formation region where localized rotational structures coexist with spheroidal matter assemblages, a disk-dominated orbital regime, a disk-edge orbital transition region, and a regime of stabilized local orbital systems. This segmented structural framework exhibits observationally consistent correspondence with complex radiative activity in galactic centers, the spatial distribution of globular clusters, flat galactic rotation curves, structural transitions at disk outskirts, and the stable establishment of planetary systems, thereby providing an integrated, rotation-based dynamical framework for interpreting galactic structure.
