Low Redshift BAL QSOS in the Eigenvector 1 Context
We attempt to characterize the geometry of Broad Absorption Line (BAL) QSOs by studying a low redshift sample of 12 sources. We find that the majority of these sources are Population A quasars as defined in Sulentic et al. (2000a, broad Hβ FWHM ≤ 4000 km s-1). A possible correlation between terminal velocity and absolute V magnitude suggests that the bolometric luminosity to black hole mass ratio Lbol/M BH is a governing factor with classical BAL sources showing the highest values. CIVλ1549 emission in classical BAL sources shows a profile blueshift that supports a disk wind/outflow scenario with a half opening angle of ≲ 50°. Observation of "secondary" mini-BAL features in the CIVλ1549 emission profile motivates us to model BALs with an additional component that may be involved with the BLR outflow and co-axial with the accretion disk.
