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…
Discovery of a Pair of Galaxies with Both Hosting X-ray Binary Candidates at
Sijia Cai, Zheng Cai, Jianwei Lyu +6
Among high-redshift galaxies, aside from active galactic nuclei (AGNs), X-ray binaries (XRBs) can be significant sources of X-ray emission. XRBs play a crucial role in galaxy evolu…
A Metal-Free Galaxy at ? Evidence of Late Population III Star Formation at Cosmic Noon
Sijia Cai, Mingyu Li, Zheng Cai +10
Star formation from metal-free gas, the hallmark of the first generation of Population III stars, was long assumed to occur only in the very early Universe. We report the discovery…
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…
A 13-Billion-Year View of Galaxy Growth: Metallicity Gradient Evolution from the Local Universe to with JWST and Archival Surveys
Zihao Li, Zheng Cai, Xin Wang +25
The galaxy gas-phase metallicity gradients have been extensively studied over the past four decades, both in the local and high-redshift universe, as they trace the baryon cycle an…
The Cosmic Owl: Twin Active Collisional Ring Galaxies with Starburst Merging Front at
Mingyu Li, Bjorn H. C. Emonts, Zheng Cai +12
Galaxy mergers play a critical role in driving galaxy evolution, especially by transforming galaxy morphology, redistributing gas around galaxies, triggering active galactic nuclei…
Lyman-Break Galaxies in the Mpc-Scale Environments Around Three Quasars With JWST Imaging
Maria Pudoka, Feige Wang, Xiaohui Fan +16
We study the Mpc-scale environments of the three highest redshift luminous quasars at (J031343.84-180636.40, J134208.11+092838.61, and J100758.27+211529.21) to understa…
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…
Bridging Quasars and Little Red Dots: Insights into Broad-Line AGNs at from the First JWST COSMOS-3D Dataset
Xiaojing Lin, Xiaohui Fan, Feige Wang +30
We report the discovery of 13 broad-line AGNs at from the first 10% data of the JWST Cycle 3 Treasury Program COSMOS-3D. These AGNs are identified by their broad H o…
JWST ASPIRE: How Did Galaxies Complete Reionization? Evidence for Excess IGM Transmission around Emitters during Reionization
Koki Kakiichi, Xiangyu Jin, Feige Wang +23
The spatial correlation between galaxies and the Ly forest provides insights into how galaxies reionized the Universe. Here, we present initial results on the spatial cross-corr…
The SUPERCOLD-CGM survey: II. [\ion{C}{1}] emission and the physical conditions of cold gas in Enormous Ly nebulae at
Jianan Li, Bjorn H. C. Emonts, Zheng Cai +13
We report ALMA and ACA observations of atomic carbon ([\ion{C}{1}]) and dust continuum in 10 Enormous Ly Nebulae hosting ultra-luminous Type-I QSOs at , as par…
