ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization
Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42
We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…
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…
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…
Fading Light, Fierce Winds: JWST Snapshot of a Sub-Eddington Quasar at Cosmic Dawn
Jianwei Lyu, George H. Rieke, Meredith Stone +6
The majority of most luminous quasars during the epoch of reionization accrete near or above the Eddington limit, marking the vigorous growth of primitive supermassive black holes…
First results from the JWST Early Release Science Program Q3D: The Fast Outflow in a Red Quasar at z=0.44
Weizhe Liu, Sylvain Veilleux, Swetha Sankar +26
Quasar feedback may play a key role in the evolution of massive galaxies. The dust-reddened quasar, F2M110648.35480712 at is one of the few cases at its redshift th…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): JWST Supports Earlier Reionization around [OIII] Emitters
Xiangyu Jin, Jinyi Yang, Xiaohui Fan +22
Understanding when and how reionization happened is crucial for studying the early structure formation and the properties of first galaxies in the Universe. At , the observe…
