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…
Extreme Neutral Outflow in a non-AGN Quiescent Galaxy at z~1.3
Yang Sun, Zhiyuan Ji, George H. Rieke +8
We report the discovery of a substantial sodium doublet (Na D 5890, 5896Ã )-traced neutral outflow in the quiescent galaxy JADES-GS-206183 at . Its JWST/NIRSpec-MSA…
The Relation Between AGN and Host Galaxy Properties in the JWST Era: II. The merger-driven evolution of Seyferts at Cosmic Noon
Nina Bonaventura, Jianwei Lyu, George H. Rieke +3
In Paper I, we exploited the unsurpassed resolution and depth of JWST/NIRCam imagery to investigate the relationship between AGN and host-galaxy properties in the JWST era, finding…
The quasar ULAS J1120+0641 May Never Reach a "Normal" Black Hole to Stellar Mass Ratio
Meredith A. Stone, George H. Rieke, Jianwei Lyu +4
JWST observations of quasars in the Epoch of Reionization have revealed that many lie in host galaxies that are severely undermassive relative to the supermassive black holes. It i…
Unveiling the Aromatic and Aliphatic Universe at Redshifts 0.2--0.5 with JWST NIRCam/WFSS
Jianwei Lyu, Xuejuan Yang, Aigen Li +4
Utilizing deep NIRCam/WFSS data from JWST's FRESCO program, we spectroscopically survey the 3.3 aromatic and 3.4 aliphatic C--H stretching emission bands of polycyclic…
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…
