The Properties of Low-Redshift FeLoBAL Quasars: III. The Location and Geometry of the Outflows
Hyunseop Choi, Karen M. Leighly, Collin Dabbieri +3
We present continued analysis of a sample of low-redshift iron low-ionization broad absorption-line quasars (FeLoBALQs). Choi et al. (2022) presented spectral analysis of…
The Physical Properties of Low-Redshift FeLoBAL Quasars: II. The Rest-Frame Optical Emission Line Properties
Karen M. Leighly, Hyunseop Choi, Cora DeFrancesco +4
We report the results of analysis of the Hbeta emission-line region of a sample of thirty low-redshift (z<1) iron low-ionization broad absorption line quasars (FeLoBALQs). Eleven o…
The Physical Properties of Low Redshift FeLoBAL Quasars. I. Spectral Synthesis Analysis of the BAL Outflows using
Hyunseop Choi, Karen M. Leighly, Donald M. Terndrup +3
We present the first systematic study of 50 low redshift () iron low-ionization broad absorption-line quasars (FeLoBALQs) using which represents a more th…
Cosmic Pathways for Compact Groups in the Milli-Millennium Simulation
P. Tzanavaris, S. C. Gallagher, S. Ali +3
We detected 10 compact galaxy groups (CGs) at in the semi-analytic galaxy catalog of Guo et al. (2011) for the milli-Millennium Cosmological Simulation (sCGs in mGuo2010a). W…
The Occurrence of Compact Groups of Galaxies Through Cosmic Time
Christopher D. Wiens, Trey V. Wenger, Panayiotis Tzanavaris +3
We use the outputs of a semi-analytical model of galaxy formation run on the Millennium Simulation to investigate the prevalence of 3D compact groups (CGs) of galaxies from $z = 11…
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…
