AI-generated Abstract
This paper discusses the identification and characteristics of extreme Broad Absorption Line (BAL) quasars discovered through the Sloan Digital Sky Survey (SDSS). The study focuses on the rare subclass of LoBAL quasars, which exhibit absorption features from both low- and high-ionization transitions, and highlights the presence of Fe ii* absorption in these objects. The authors note significant reddening in extreme BAL quasars and explore the implications of this for understanding quasar outflows and the environments in which these quasars reside.
