Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. I.Sample from the Early Data
Wei-Jian Guo, Hu Zou, Victoria Anne Fawcett +34
Changing-look Active Galactic Nuclei (CL AGN) can be generally confirmed by the emergence (turn-on) or disappearance (turn-off) of broad emission lines, associated with a transient…
Astrometric Calibration of the BeijingArizona Sky Survey
Xiyan Peng, Zhaoxiang Qi, Tianmeng Zhang +13
We present the astrometric calibration of the Beijing-Arizona Sky Survey (BASS). The BASS astrometry was tied to the International Celestial Reference Frame via the \emph{Gaia} Dat…
The Sloan Digital Sky Survey Reverberation Mapping Project: Key Results
Yue Shen, Catherine J. Grier, Keith Horne +44
We present the final data from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project, a precursor to the SDSS-V Black Hole Mapper Reverberation Mapping program. This…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): JWST Reveals a Filamentary Structure around a z=6.61 Quasar
Feige Wang, Jinyi Yang, Joseph F. Hennawi +56
We present the first results from the JWST ASPIRE program (A SPectroscopic survey of biased halos In the Reionization Era). This program represents an imaging and spectroscopic sur…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): A First Look at the Rest-frame Optical Spectra of Quasars Using JWST
Jinyi Yang, Feige Wang, Xiaohui Fan +53
Studies of rest-frame optical emission in quasars at have historically been limited by the wavelengths accessible by ground-based telescopes. The James Webb Space Telescope (…
(SHERRY) JCMT-SCUBA2 High Redshift Bright Quasar Survey -- II: the environment of z~6 quasars in sub-millimeter band
Qiong Li, Ran Wang, Xiaohui Fan +14
The formation of the first supermassive black holes is expected to have occurred in some most pronounced matter and galaxy overdensities in the early universe. We have conducted a…
