The MIRI Early Obscured-AGN Wide Survey (MEOW): A Population of Hidden AGN at Revealed by JWST/MIRI Imaging

Gene C. K. Leung, Anna-Christina Eilers, Ryan Endsley +25

We present the MIRI Early Obscured-AGN Wide Survey (MEOW), a JWST/MIRI imaging survey designed to detect dust-obscured active galactic nuclei (AGN) across cosmic time, with a parti…

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…

Probing Direct Contributions of Galaxies and AGN to Cosmic Reionization in a Quasar Field J0226+0302 with JWST NIRCam and NIRSpec

Xiangyu Jin, Jinyi Yang, Feige Wang +19

We present JWST Cycle 2 NIRCam and NIRSpec observations in a quasar field J0226+0302 at z=6.5412 to probe the direct connections between the intergalactic medium (IGM), galaxies, a…

Chaotic Molecular Gas in Five Dusty Star-forming Galaxies in the Spiderweb Protocluster at

Jaclyn B. Champagne, Helmut Dannerbauer, Jose Manuel Perez-Martinez +4

Measuring the properties of cold molecular gas available for intense star formation in galaxy protoclusters at is a crucial step in understanding large scale structure format…

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…

MIGHTEE/COSMOS-3D: The discovery of three spectroscopically confirmed radio-selected star-forming galaxies at z=4.9-5.6

R. G. Varadaraj, A. Saxena, S. Fakiolas +10

Radio observations offer a dust-independent probe of star formation and active galactic nucleus (AGN) activity, but sufficiently deep data are required to access the crossover lumi…
