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…
The Extreme Rarity and Physical Properties of Low-redshift AGNs with Balmer Absorption
Jinyi Shangguan, Chang-Hao Chen, Luis C. Ho +6
Balmer absorption lines are increasingly observed in the little red dots (LRDs) discovered by the James Webb Space Telescope, potentially tracing dense circumnuclear gas around rap…
Halo assembly bias in the early Universe: a clustering probe of the origin of the Little Red Dots
Zihao Wang, Fangzhou Jiang, Haonan Zheng +5
The clustering of galaxies encodes key information about the structure and assembly history of their host dark matter (DM) haloes, providing a powerful probe of the origin of extre…
Local Analogs of Little Red Dots: Optical Variability and Evidence for an Active Galatic Nucleus Origin
Ruqiu Lin, Zhen-Ya Zheng, Junxian Wang +9
Little red dots (LRDs) draw extensive attention because of their unique observational characteristics and apparent overabundance in the early Universe, raising new insights into ea…
Little red dot variability over a century reveals black hole envelope via a giant Einstein cross
Zijian Zhang, Mingyu Li, Masamune Oguri +79
"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…
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…
Estimating Bolometric Luminosities of Type 1 Quasars with Self-Organizing Maps
Jie Chen, Linhua Jiang, Shengxiu Sun +2
We present a new method to calculate bolometric luminosities for unobscured, type 1 quasars with multi-band photometric data. Bolometric luminosity is a fundamental property to und…
Introduction to the Chinese Space Station Survey Telescope (CSST)
CSST Collaboration, Yan Gong, Haitao Miao +119
The Chinese Space Station Survey Telescope (CSST) is an upcoming Stage-IV sky survey telescope, distinguished by its large field of view (FoV), high image quality, and multi-band o…
JWST Insights into Narrow-line Little Red Dots
Zijian Zhang, Linhua Jiang, Weiyang Liu +2
James Webb Space Telescope (JWST) has revealed a population of red and compact objects with a unique V-shape SED at z >= 4 known as Little Red Dots (LRDs). Most of the LRDs with ex…
Discovery of Local Analogs to JWST's Little Red Dots
Ruqiu Lin, Zhen-Ya Zheng, Chunyan Jiang +12
Recently, the James Webb Space Telescope (JWST) has revealed a new class of high redshift (high-, ) compact galaxies which are red in the rest-frame optical and blue in the…
Analysis of Multi-epoch JWST Images of Little Red Dots: Tentative Detection of Variability in a Minority of Sources
Zijian Zhang, Linhua Jiang, Weiyang Liu +1
James Webb Space Telescope (JWST) has revealed a population of red and compact sources at known as ``Little Red Dots'' (LRDs) that are likely active galactic nuclei (…
Intermediate-Mass Black Holes in Green Pea Galaxies (IMBH-GP) I: a Candidate Sample from LAMOST and SDSS
Ruqiu Lin, Zhen-Ya Zheng, Fang-Ting Yuan +8
The scaling relation of central massive black holes (MBHs) and their host galaxies is well-studied for supermassive BHs (SMBHs, ). However, th…
