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…

The Physical Properties of Low Redshift FeLoBAL Quasars. IV. Optical-Near IR Spectral Energy Distributions and Near-IR Variability Properties

Karen M. Leighly, Hyunseop Choi, Michael Eracleous +3

We present the optical-near infrared spectral energy distributions (SED) and near infrared variability properties of 30 low-redshift iron low-ionization Broad Absorption Line quasa…

Gemini Near Infrared Spectrograph -- Distant Quasar Survey: Augmented Spectroscopic Catalog and a Prescription for Correcting UV-Based Quasar Redshifts

Brandon M. Matthews, Cooper Dix, Ohad Shemmer +13

Quasars at most often have redshifts measured from rest-frame ultraviolet emission lines. One of the most common such lines, C IV , shows blueshifts up to ${…

Shedding New Light on Weak Emission-Line Quasars in the C-H Parameter Space

Trung Ha, Cooper Dix, Brandon M. Matthews +20

Weak emission-line quasars (WLQs) are a subset of Type 1 quasars that exhibit extremely weak LyN V 1240 and/or C IV 1549 emission lines. We investigate the relationship b…
