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…
An Updated Characterization of Luminous Lyα emitters at the End of Reionization
Yuanhang Ning, Zheng Cai, Linhua Jiang +5
We present a multi-wavelength physical characterization of 14 luminous Ly emitters (LAEs) at , integrating deep ground-based Magellan/M2FS spectroscopy with heteroge…
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…
Revised AGN Spectral Model Reveals a More Significant Role in Cosmic Reionization
Tong Su, Qi Guo, Wenxiang Pei +1
Reionization marks one of the most important phase transitions in the history of the Universe, during which neutral baryonic matter was transformed into ionized plasma. While star-…
