| As we have
discussed, inner AGN |
||||||||
| structure
believed to feature a black |
||||||||
| hole fed by an
accretion disk. Jets |
||||||||
| may emerge
along the spin axis, |
||||||||
| and the disk
illuminates BLR and |
||||||||
| NLR
clouds. A dense molecular |
||||||||
| torus exists
on larger scales and |
||||||||
| can obscure
the central engine |
||||||||
| from certain lines of
sight. |

Models” explain some of the different classes of AGN, |

type 1 and type 2 Seyferts, via orientation. |

specifics, see the Annual Reviews article by Antonucci, 1993, a |

in the “Church of Unification.” |
