Large-scale Environmental Dependence of AGN Activity Revealed by JWST Pa Emitters
Danyang Jiang, Linhua Jiang, Shuqi Fu +7
The role of the large-scale environment in regulating AGN activity remains an open question. We investigate the Mpc-scale environments of 70 AGNs at - using a highly co…
Hot Molecular Hydrogen in Galaxies at Redshift ~ 0.2-1.5 Revealed by JWST
Jie Chen, Linhua Jiang, Shuqi Fu +5
Molecular hydrogen (H) is the fundamental component of the molecular gas reservoir that fuels star formation and black hole growth. While prominent hot H emission ($\gtrsim…
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…
Environmental dependence of the Mass-Metallicity Star Formation Relations at z=4-10 with JWST
Qiong Li, Christopher J. Conselice, Lewi Westcott +8
We study how environment affects the mass-metallicity relation (MZR) at - using deep imaging and spectroscopy from the James Webb Space Telescope (JWST). Combining CEERS a…
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…
Discovery of two little red dots transitioning into quasars
Shuqi Fu, Zijian Zhang, Danyang Jiang +9
James Webb Space Telescope (JWST) has uncovered a new population of compact objects that show a unique V-shaped spectral energy distribution (SED) in the UV and optical wavelength…
COSMOS-3D: Dense Circumnuclear Gas across Black Hole Growth Phases at z ~ 3
Zi-Jian Li, Siwei Zou, Jianwei Lyu +25
We report the discovery of two broad-line X-ray AGNs (cid_414 and cid_947) at z ~ 3 identified in the JWST Cycle 3 COSMOS-3D program using NIRCam F444W grism spectroscopy. Both exh…
Medium-band Astrophysics with the Grism of NIRCam In Frontier fields (MAGNIF): Spectroscopic Census of H Luminosity Functions and Cosmic Star Formation at and 6.3
Shuqi Fu, Fengwu Sun, Linhua Jiang +35
We measure H luminosity functions (LFs) at redshifts and 6.3 using the JWST MAGNIF (Medium-band Astrophysics with the Grism of NIRCam In Frontier fields) survey. MA…
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…
Constraints on the variation of the fine-structure constant at 3<z<10 with JWST emission-line galaxies
Linhua Jiang, Shuqi Fu, Feige Wang +7
We present constraints on the spacetime variation of the fine-structure constant at redshifts using JWST emission-line galaxies. The galaxy sample consists of 62…
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…
An Hα Impression of Lyα Galaxies at with Deep JWST/NIRCam Imaging
Yuanhang Ning, Zheng Cai, Linhua Jiang +3
We present a study of seven spectroscopically confirmed (Ly emitting) galaxies at redshift using the /NIRCam imaging data. These galaxies, with a wide range of…
The Nature of Luminous Quasars with Very Large C IV Equivalent Widths
Shuqi Fu, W. N. Brandt, Fan Zou +5
We report results for a complete sample of ten luminous radio-quiet quasars with large C IV equivalent widths (EW > 150 A). For 8/10 we performed Chandra snapshot observations. We…
