Balmer Absorption in Iron Low-Ionization Broad Absorption Line Quasars
Karen M. Leighly, Sarah C. Gallagher, Hyunseop Choi +4
While C IV is the most common absorption line in Broad Absorption Line Quasar spectra, Balmer absorption lines are among the rarest. We present analysis of Balmer absorption in a s…

Investigating the {Origin} of the Absorption-Line Variability in Narrow-Line Seyfert 1 Galaxy WPVS 007
Kaylie S. Green, Sarah C. Gallagher, Karen M. Leighly +5
Broad Absorption Line Quasars (BALQs) are actively accreting supermassive black holes that have strong outflows characterized by broad absorption lines in their rest-UV spectra. Va…
