| Abstract: |
We present high signal-to-noise spectropolarimetry of the Broad
Absorption Line QSO (BALQSO) PG 1700+518. Modeling of the polarization
in this object, aspects of which were first reported in Young et al. (2007),
confirms that in order to reproduce the variations in
θ(λ) across Hα, scattering must predominantly take
place in a rising hollow cylinder. The main scattering region is rising
vertically off the accretion disk at a velocity close to the local
Keplerian velocity and rotating about the system axis. Additionally,
the scattering region is launched from a region in the accretion disk
close to where the BLR originates and extends to a height significantly
greater than inner launch radius. |
