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…
A Deep Chandra X-ray Survey of a Luminous Quasar Sample at 7
Xiangyu Jin, Feige Wang, Jinyi Yang +11
We present new Chandra observations of seven luminous quasars at . Combined with archival Chandra observations of all other known quasars, they form nearly complete X-ray ob…
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…
A JWST/NIRSpec Integral Field Unit Survey of Luminous Quasars at z ~ 5-6 (Q-IFU): Rest-frame Optical Nuclear Properties and Extended Nebulae
Weizhe Liu, Xiaohui Fan, Richard Green +10
It remains debatable how billion-solar-mass supermassive black holes (SMBHs) form and evolve within the first billion years. We report results from a James Webb Space Telescope (JW…
JWST COSMOS-3D: Spectroscopic Census and Luminosity Function of [O III] Emitters at 6.75<z<9.05 in COSMOS
Romain A. Meyer, Feige Wang, Koki Kakiichi +38
We present a catalogue of spectroscopically selected [OIII]+Hb emitters at 6.75<z<9.05 and the resulting [OIII] 5008 ÅLuminosity Function (LF) in the COSMOS field. We leverage the…
Quasar Radiative Feedback May Suppress Galaxy Growth on Intergalactic Scales at
Yongda Zhu, Eiichi Egami, Xiaohui Fan +27
We present observational evidence that intense ionizing radiation from a luminous quasar suppresses nebular emission in nearby galaxies on intergalactic scales at . Using JW…
New Insight from the James Webb Space Telescope on Variable Active Galactic Nuclei
Bangzheng Sun, Haojing Yan, Wei Leong Tee +1
Variability detected in galaxies is usually attributed to their active galactic nuclei (AGNs). While all AGNs are intrinsically variable, the AGN unification model predicts that ty…
The Discovery of Little Red Dots in the Local Universe: Signatures of Cool Gas Envelopes
Xiaojing Lin, Xiaohui Fan, Zheng Cai +25
JWST observations have revealed a population of high-redshift "little red dots" (LRDs) that challenge conventional AGN models. We report the discovery of three local LRDs at $z = 0…
The Identification of Two JWST/NIRCam-Dark Starburst Galaxies at with ALMA
Fengwu Sun, Jinyi Yang, Feige Wang +20
We analyze two dusty star-forming galaxies at . These galaxies are selected from the ASPIRE survey, a JWST Cycle-1 medium and ALMA Cycle-9 large program targeting 25 quasars…
Enhanced Merger Fractions in a Reionization-Era Protocluster
Lorraine C. Marcelin, Jaclyn B. Champagne, Feige Wang +4
Mergers play a critical role in galaxy evolution, but their relationship to their surrounding environments is unexplored at high redshift. We investigate the galaxy merger rate amo…
SAPPHIRES: Extremely Metal-Poor Galaxy Candidates with at from Deep JWST/NIRCam Grism Observations
Tiger Yu-Yang Hsiao, Fengwu Sun, Xiaojing Lin +19
Population III stars, the hypothetical first generation metal-free stars, have yet to be discovered. Even after three years of successful JWST operations, studies have shown that m…
