摘要

We present a cyclic model of galaxy evolution deriving bars and peculiar structure. Conceptual 'toy' models are important tools supporting simulations. We correlate SDSS, kinetic and other survey findings, and present evidence of an iterative process powered by galactic nuclei (AGN) orbital angular momentum. Focused on the "quasar-era's" at z~>6>>z~1.7 AGN's accrete, re-ionize and eject disc matter in collimated jets on the disc axis. Assumed feedback to discs is replaced by disc clearance and creation of a new open spiral on the new perpendicular axis of re-ionized jet matter. The bar half-length is the virial radius. Spiral arms formed from the jet matter tighten and blend into discs as commonly assumed. We find accretion forms lenticular bulges as outflows create the lobes. Rings may men result from accretion. A cycle of active quasar population was identified at ~10Gyr by Martini-Weinberg (2001). Metallicity/star-forming evolution suggests similar 'multiple infall' events (Micali-Matteucci-Romano (2013). We predict a tranche of anomalous observed phenomena including superluminal jets consistent with a Friedman universe, halo kinematic decoupling, anisotropic mass growth at z~6 and z~2, the accompanying re-ionization of H and He in turn, single age dwarf satellite galaxies and the Magellanic stream.
