      Line Region

Abstract: 
  Polarization is a useful probe to investigate the geometries and dynamics of 
outflows in BAL QSOs. We perform a Monte-Carlo method to simulate the polarization 
produced by resonant and electron scattering in BALR. We find a rotated and 
funnel-shaped thin shell outflow is preferred to explain many observed 
polarization features.
