Gemini Near Infrared Spectrograph -- Distant Quasar Survey: Augmented Spectroscopic Catalog and a Prescription for Correcting UV-Based Quasar Redshifts
Brandon M. Matthews, Cooper Dix, Ohad Shemmer +13
Quasars at most often have redshifts measured from rest-frame ultraviolet emission lines. One of the most common such lines, C IV , shows blueshifts up to ${…
Radio AGN Selection and Characterization in Three Deep-Drilling Fields of the Vera C. Rubin Observatory Legacy Survey of Space and Time
Shifu Zhu, William N. Brandt, Fan Zou +4
The Australia Telescope Large Area Survey (ATLAS) and the VLA survey in the XMM-LSS/VIDEO deep field provide deep ( Jybeam) and high-resolution ( 4.5…
Shedding New Light on Weak Emission-Line Quasars in the C-H Parameter Space
Trung Ha, Cooper Dix, Brandon M. Matthews +20
Weak emission-line quasars (WLQs) are a subset of Type 1 quasars that exhibit extremely weak LyN V 1240 and/or C IV 1549 emission lines. We investigate the relationship b…
The Sloan Digital Sky Survey Reverberation Mapping Project: The Black Hole MassStellar Mass Relations at
Jennifer I-Hsiu Li, Yue Shen, Luis C. Ho +7
We measure the correlation between black-hole mass and host stellar mass for a sample of 38 broad-line quasars at (median redshift $z…
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 Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
