Power Source for Active Galaxies and Quasars If there is a strong magnetic field in the accretion disk, the magnetic field lines can be distorted into a tangled, narrow mess of magnetic field lines that run toward the poles perpendicular to the accretion disk. Gas escaping along the magnetic field would produce the beams of electrons and gas seen in the jets to make the radio lobes of radio galaxies. Also, the shape of the accretion disk may play a role in directing the gas into the jets. The outer parts of the disk can be thick, but they will narrow down to a very thin layer just outside of the black hole. A thick accretion disk that narrows down only very close to the black hole could pinch the outflowing gas into a narrow beam. Around the accretion disk are relatively dense clouds of hot gas that could be responsible for the broad emission lines seen in Type 1 Seyferts. Further out is a thick dusty molecular doughnut- shaped ring with a diameter of ten to several hundred light years. The particular type of active
