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…
Reconstructing Robust Background IFU spectra using Machine Learning
Carter Lee Rhea, Julie Hlavacek-Larrondo, Justine Giroux +6
In astronomy, spectroscopy consists of observing an astrophysical source and extracting its spectrum of electromagnetic radiation. Once extracted, a model is fit to the spectra to…
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…
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…
Discovery of a Remarkably Powerful Broad Absorption Line Quasar Outflow in SDSS J135246.37+423923.5
Hyunseop Choi, Karen M. Leighly, Donald M. Terndrup +2
Broad absorption line (BAL) features in quasar spectra reveal an unambiguous signature of energetic outflows from central supermassive black holes, and thus BAL quasars are prime t…
Astro2020 APC White Paper: Accessible Astronomy: Policies, Practices, and Strategies to Increase Participation of Astronomers with Disabilities
Alicia Aarnio, Nicholas Murphy, Karen Knierman +14
(Abridged) In this white paper, we outline the major barriers to access within the educational and professional practice of astronomy. We present current best practices for inclusi…
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…
Demographics of Sloan Digital Sky Survey galaxies along the Hubble sequence
Kyuseok Oh, Hyunseop Choi, Hong-Geun Kim +2
We present the statistical properties of a volume-limited sample of 7,429 nearby (z = 0.033 - 0.044) galaxies from the Sloan Digital Sky Survey Data Release 7. Our database include…
