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…
Fast and Flexible Inference Framework for Continuum Reverberation Mapping using Simulation-based Inference with Deep Learning
Jennifer I-Hsiu Li, Sean D. Johnson, Camille Avestruz +5
Continuum reverberation mapping (CRM) of active galactic nuclei (AGN) monitors multiwavelength variability signatures to constrain accretion disk structure and supermassive black h…
Understanding the Broad-line Region of Active Galactic Nuclei with Photoionization. I. the Moderate-Accretion Regime
Qiaoya Wu, Yue Shen, Hengxiao Guo +9
Over three decades of reverberation mapping (RM) studies on local broad-line active galactic nuclei (AGNs) have measured reliable black-hole (BH) masses for AGNs. These RM…
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…
Prior-Informed AGN-Host Spectral Decomposition Using PyQSOFit
Wenke Ren, Hengxiao Guo, Yue Shen +4
We introduce an improved method for decomposing the emission of active galactic nuclei (AGN) and their host galaxies using templates from principal component analysis (PCA). This a…
High-quality Extragalactic Legacy-field Monitoring (HELM) with DECam
Ming-Yang Zhuang, Qian Yang, Yue Shen +45
High-quality Extragalactic Legacy-field Monitoring (HELM) is a long-term observing program that photometrically monitors several well-studied extragalactic legacy fields with the D…
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…
