An Exploratory Analysis of New Large Gaia-informed Quasar Samples in SDSS-V
Shir Aviram, Benny Trakhtenbrot, Tom Dwelly +22
Quasars are luminous objects that provide insights into the physics and evolution of supermassive black holes (SMBHs) and their accretion flows, galaxy evolution, and even cosmolog…
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…
A New Member of the Fast and Furious Family: A Relativistic and Time-Variable UV Outflow in a Luminous Quasar
Lucas M. Seaton, Patrick B. Hall, Liliana Flores +20
We report the fastest quasar outflow first detected in the ultraviolet, via variable C IV and Si IV absorption at outflow velocities km s to at least km…
CIV wind properties of the SDSS-V X-ray selected quasars: strong optical-to-UV emission is key regardless of X-ray strength
Amy L. Rankine, David Homan, James Aird +25
We present an investigation of the rest-frame optical/UV and X-ray properties for a sample of 3027 X-ray selected quasars between detected in the deepest Spec…
Discovery of the First Five Carbon-Enhanced Metal-Poor Stars in the LMC
Madeline Lucey, Vedant Chandra, Alexander Ji +7
A substantial fraction of metal-poor stars in the local Milky Way halo exhibit large overabundances of carbon. These stars, dubbed Carbon-Enhanced Metal-Poor (CEMP) stars, provide…
The SDSS-V Black Hole Mapper Reverberation Mapping Project: Light Echoes of the Coronal Line Region in a Luminous Quasar
Theodore B. Smith, Logan B. Fries, Jonathan R. Trump +19
We present a reverberation mapping analysis of the coronal line [Ne V]3427 emitting region of the quasar COS168 (SDSS J095910.30+020732.2). [Ne V]3427 is known as one of the…
The large-scale kinematics of young stars in the Milky Way disc: first results from SDSS-V
Eleonora Zari, Jaime Villaseñor, Marina Kounkel +17
We present a first large-scale kinematic map of 50,000 young OB stars ( K), based on BOSS spectroscopy from the Milky Way Mapper OB program in the on…
X-ray selected broad absorption line quasars in SDSS-V: BALs and non-BALs span the same range of X-ray properties
Pranavi Hiremath, Amy L. Rankine, James Aird +10
Broad absorption line (BAL) quasars are often considered X-ray weak relative to their optical/UV luminosity, whether intrinsically (i.e., the coronal emission is fainter) or due to…
Mapping the Distant and Metal-Poor Milky Way with SDSS-V
Vedant Chandra, Phillip A. Cargile, Alexander P. Ji +28
The fifth-generation Sloan Digital Sky Survey (SDSS-V) is conducting the first all-sky low-resolution spectroscopic survey of the Milky Way's stellar halo. We describe the stellar…
Optical Emission-Line Properties of eROSITA-selected SDSS-V Galaxies
Nadiia G. Pulatova, Evgenii Rubtsov, Igor V. Chilingarian +21
We present and discuss optical emission line properties obtained from the analysis of Sloan Digital Sky Survey (SDSS) spectra for an X-ray selected sample of 3684 galaxies (0.002 <…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
The SDSS-V Black Hole Mapper Reverberation Mapping Project: A Kinematically Variable Broad-Line Region and Consequences for Masses of Luminous Quasars
Logan B. Fries, Jonathan R. Trump, Keith Horne +27
We present a velocity-resolved reverberation mapping analysis of the hypervariable quasar RM160 (SDSS J141041.25+531849.0) at z = 0.359 with 153 spectroscopic epochs of data repres…
The SDSS-V Black Hole Mapper Reverberation Mapping Project: Multi-Line Dynamical Modeling of a Highly Variable Active Galactic Nucleus with Decade-long Light Curves
Zachary Stone, Yue Shen, Scott F. Anderson +15
We present dynamical modeling of the broad-line region (BLR) for the highly variable AGN SDSS J141041.25+531849.0 () using photometric and spectroscopic monitoring data…
The SDSS-V Black Hole Mapper Reverberation Mapping Project: CIV BAL Acceleration in the Quasar SBS 1408+544
Robert Wheatley, Catherine J. Grier, Patrick B. Hall +20
We present the results of an investigation of a highly variable CIV broad absorption-line feature in the quasar SBS 1408+544 (z=2.337) that shows a significant shift in velocity ov…
Exploring Changing-look Active Galactic Nuclei with the Sloan Digital Sky Survey V: First Year Results
Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous +32
"Changing-look" active galactic nuclei (CL-AGNs) challenge our basic ideas about the physics of accretion flows and circumnuclear gas around supermassive black holes. Using first-y…
