The Structure of BAL QSOs

Dr. Patrick Ogle, MIT


I will discuss the polarization properties of broad absorption line quasars (BAL QSOs), and what we can learn about their structure from their polarization spectra. The relatively high polarization and polarization distribution of BAL QSOs is consistent with their unification with non-BAL QSOs. Line polarization measurements also indicate that the BAL outflow has a small global covering fraction and is confined to equatorial or intermediate latitudes.
