Luminosity function of quasars at from SDSS and DESI
Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54
We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…
Changing-Look AGNs from DESI. VI. Host Galaxies
Shengxiu Sun, Linhua Jiang, Wei-Jian Guo +2
Changing-look (CL) AGNs trace rapid changes in nuclear activity, but their connection to host galaxy properties remains unclear. We present a study of the host galaxies of 105 CL A…
Quiescent Host Galaxies of Extended Quasars Revealed by Spectrophotometric Decomposition
Shengxiu Sun, Linhua Jiang, Zhiwei Pan +27
Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies. Here we present a study of…
A Rare Eddington-Limited, Heavily Obscured Low-Mass Active Galactic Nucleus Likely Triggered by a Galaxy Merger
Shouyi Wang, Fan Zou, Chang-Hao Chen +7
We report a detailed analysis of GAMA 376183, a powerful, heavily obscured active galactic nucleus (AGN) hosted by a low-mass galaxy () likely ex…
COSMOS-3D: Black Hole Mass Estimators and Luminosity Functions of Paschen-line AGNs
Danyang Jiang, Linhua Jiang, Shuqi Fu +13
Near-IR Paschen lines are potentially an excellent tracer of Type 1 AGNs that is hardly affected by dust extinction. JWST allows us, for the first time, to explore Paschen-line obj…
Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. V. Dramatic Variability in High-Ionization Broad Emission Lines
Zhi-Qiang Chen, Jun-Jie Jin, Wei-Jian Guo +10
We present a systematic search for changing-look (CL) quasars at high redshift z > 0.9 by cross-matching the spectroscopic datasets from the Dark Energy Spectroscopic Instrument Da…
