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…
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…
Quasar Outflow Deceleration or Acceleration: Predictions and a Search
Patrick B. Hall, E. Weiss, W. N. Brandt +1
Quasar winds can shock and sweep up ambient interstellar medium (ISM) gas, contributing to galactic quenching. We combine and extend past models of energy-conserving shock bubbles…
Quasar winds caught on acceleration and deceleration
Weimin Yi, P. B. Hall, Zunlin Yuan +5
We present an observational study of wind acceleration based on four low-ionization broad absorption line (LoBAL) quasars (J0136, J1238, J1259, J1344). J0136 and J1344 (group-1) ar…
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…
