The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
Simulating Disky Broad Line Region Reverberation
Mary Ogborn, Michael Eracleous, Jessie C. Runnoe +3
Variability studies of the broad emission lines of Active Galactic Nuclei (AGNs) and quasars show stochastic radial velocity variations (i.e., fluctuations in the centroid of the l…
The Tantalizing Case of the Quasar J0950+5128 -- I. Presentation of the Data and Detailed Exploration of the Binary Supermassive Black Hole Scenario
Niana N. Mohammed, Jessie C. Runnoe, Michael Eracleous +8
Spectroscopic observations of the quasar J09505128 spanning 22 years reveal monotonic radial velocity variations in its broad H emission line. Moreover, the line profile beco…
The SDSS-V Black Hole Mapper Reverberation Mapping Project: Unusual Broad-Line Variability in a Luminous Quasar
Logan B. Fries, Jonathan R. Trump, Megan C. Davis +30
We present a high-cadence multi-epoch analysis of dramatic variability of three broad emission lines (MgII, H, and H) in the spectra of the luminous quasar ((5100Å) = $…
The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
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. 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…
