H Line Widths as an Orientation Indicator for Low-Ionization Broad Absorption Line Quasars

Brian Punsly, Shaohua Zhang

There is evidence from radio-loud quasars to suggest that the distribution of the H broad emission line (BEL) gas is arranged in a predominantly planar orientation, and this res…

Low-z MgII Broad Absorption-Line Quasars from the Sloan Digital Sky Survey

Shaohua Zhang, Ting-Gui Wang, Huiyuan Wang +3

We present a sample of 68 low-z MgII low-ionization broad absorption-line (loBAL) quasars. The sample is uniformly selected from the SDSS5 according to the following criteria: (1)…
