A JWST View of Cosmic Star Formation from to 9 with Hydrogen Recombination Lines in the COSMOS and GOODS-N fields
Shuqi Fu, Linhua Jiang, Christopher J. Conselice +9
We combine wide-area COSMOS-3D observations with deeper GOODS-N data from JWST/NIRCam F444W wide-field slitless spectroscopy to trace cosmic star formation over --9. The ob…
COSMOS-3D: Diverse Environments and Hot-dust Signatures among Dusty Star-forming Galaxies at = 4.9-7.2
Siwei Zou, Manuel Aravena, Shaoze Geng +20
Dusty star-forming galaxies (DSFGs) are expected to trace early massive-halo assembly, but the connection between dust-obscured star formation, morphology, hot dust, and environmen…
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…
Broad Paschen lines as black hole mass tracers: A reverberation mapping calibration
Shengxiu Sun, Sarah E. I. Bosman, Frederick B. Davies +4
Single-epoch (SE) black hole mass estimators based on rest-frame ultraviolet or optical broad lines can be limited by dust attenuation or wavelength coverage. We calibrate estimato…
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 heterogen…
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-…
Iron-corrected Single-epoch Black Hole Masses of DESI Quasars at low redshift
Zhiwei Pan, Linhua Jiang, Wei-Jian Guo +31
We present a study on the possible overestimation of single-epoch supermassive black hole (SMBH) masses in previous works, based on more than 55,000 type 1 quasars at $0.25 < z < 0…
AGN ruled out as the dominant source of cosmic reionization
Danyang Jiang, Linhua Jiang, Shengxiu Sun +2
Cosmic reionization represents the latest phase transition in the Universe, when the Lyman continuum (LyC) photons turned the intergalactic medium (IGM) from neutral to highly ioni…
No Redshift Evolution in the Fe II/Mg II Flux Ratios of Quasars across Cosmic Time
Danyang Jiang, Masafusa Onoue, Linhua Jiang +13
The Fe II/Mg II emission line flux ratio in quasar spectra serves as a proxy for the relative Fe to alpha-element abundances in the broad line regions of quasars. Due to the expect…
The Magellan M2FS spectroscopic survey of high-redshift galaxies: the brightest Lyman-break galaxies at
Shuqi Fu, Linhua Jiang, Yuanhang Ning +2
We present a study of a sample of 45 spectroscopically confirmed, UV luminous galaxies at . They were selected as bright Lyman-break galaxies (LBGs) using deep multi-band…
Quantifying the escape of Ly at : a census of Ly escape fraction with H emitting galaxies spectroscopically confirmed by JWST and VLT/MUSE
Xiaojing Lin, Zheng Cai, Yunjing Wu +11
JWST provides an unprecedented opportunity for unbiased surveys of H-emitting galaxies at with the NIRCam wide-field slitless spectroscopy (WFSS). In this work, we present…
