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…
First constraints on the local ionization topology in front of two quasars at z ~ 7.5
Timo Kist, Joseph F. Hennawi, Frederick B. Davies +10
Thus far, Lyman- damping wings towards quasars have been used to probe the \textit{global} ionization state of the foreground intergalactic medium (IGM). A new parameterization…
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…
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…
SAPPHIRES: A Galaxy Over-Density in the Heart of Cosmic Reionization at
Yoshinobu Fudamoto, Jakob M. Helton, Xiaojing Lin +17
We report the discovery of a galaxy proto-cluster candidate (dubbed MACS0416-OD-z8p5) at a spectroscopic redshift of , dating back to Myr after the Big Bang. Th…
