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 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…

Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy

Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217

The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…

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: 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…

The Sloan Digital Sky Survey Reverberation Mapping Project: Investigation of Continuum Lag Dependence on Broad-Line Contamination and Quasar Properties

Hugh W. Sharp, Y. Homayouni, Jonathan R. Trump +16

This work studies the relationship between accretion-disk size and quasar properties, using a sample of 95 quasars from the SDSS-RM project with measured lags between the and $…

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) = $…

A Transient "Changing-look'' Active Galactic Nucleus Resolved on Month Timescales from First-year Sloan Digital Sky Survey V Data

Grisha Zeltyn, Benny Trakhtenbrot, Michael Eracleous +32

We report the discovery of a new ``changing-look'' active galactic nucleus (CLAGN) event, in the quasar SDSS J162829.17+432948.5 at z=0.2603, identified through repeat spectroscopy…

Studying the Physical Properties of Tidal Features I. Extracting Morphological Substructure in CANDELS Observations and VELA Simulations

Kameswara Bharadwaj Mantha, Daniel H. McIntosh, Cody P. Ciaschi +17

The role of major mergers in galaxy evolution remains a key open question. Existing empirical merger identification methods use non-parametric and subjective visual classifications…
