Discovery of the most luminous quasar of the last 9 Gyr
Christopher A. Onken, Samuel Lai, Christian Wolf +8
We report the discovery of a bright (g = 14.5 mag (AB), K = 11.9 mag (Vega)) quasar at redshift z = 0.83 -- the optically brightest (unbeamed) quasar at z > 0.4. SMSS J114447.77-43…
The z=0.54 LoBAL Quasar SDSS J085053.12+445122.5: II. The Nature of Partial Covering in the Broad-Absorption-Line Outflow
Karen M. Leighly, Donald M. Terndrup, Adrian B. Lucy +5
It has been known for 20 years that the absorbing gas in broad absorption line quasars does not completely cover the continuum emission region, and that partial covering must be ac…
The Binary Black Hole Model for Mrk 231 Bites the Dust
Karen M. Leighly, Donald M. Terndrup, Sarah C. Gallagher +1
Mrk 231 is a nearby quasar with an unusually red near-UV-to-optical continuum, generally explained as heavy reddening by dust (e.g., Leighly et al. 2014). Yan et al. 2015 proposed…
Evidence for AGN Feedback in the Broad Absorption Lines and Reddening of Mrk 231
Karen M. Leighly, Donald M. Terndrup, Eddie Baron +3
We present the first J-band spectrum of Mrk 231, which reveals a large \ion{He}{1}* broad absorption line with a profile similar to that of the well-known \ion{Na}{1} broad…
Tracing the Outflow of a z=0.334 FeLoBAL: New Constraints from Low-Ionization Absorbers in FBQS J1151+3822
Adrian B. Lucy, Karen M. Leighly, Donald M. Terndrup +2
We show for the first time that FBQS J1151+3822 is an iron low-ionization broad absorption line quasar (FeLoBAL QSO), the second-brightest and second-closest known example of this…
