Low Redshift BAL QSOs in the Eigenvector 1 Context

Marziani, P.; Zamanov, R.; Braito, V. +4 more

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 HbetaFWHM ≤ 4000 km s(-1) ). A possible correlation between terminal velocity and absolute V magnitude suggests …
