Deep X-ray View of a Distant Protocluster Anchored by a Quasar at : No Evidence for Enhanced X-ray AGN Activity

Shouyi Wang, Feige Wang, Jinyi Yang +22

Whether dense environments accelerate SMBH growth during cosmic reionization remains uncertain because X-ray constraints on protoclusters are rare. We analyze ks of…

A 210 Megaparsec Ionized Structure at Revealed by an Astrophysics Foundation Model

Minghao Yue, Yongda Zhu, Jiani Ding +2

Reionization is the last major transition in the Universe that transforms the intergalactic medium (IGM) from neutral to highly ionized, yet its spatial structure remains poorly co…

Learning JWST. I. A Foundation Model for New Population Discoveries and Morphology-Aware Photometric Redshift Measurements in the JADES Survey

Jiani Ding, Minghao Yue, Yongda Zhu +2

We present FM-JADES-v1, a self-supervised foundation model for James Webb Space Telescope ({\em JWST}) deep-field science, trained with 482,444 objects from the {\em JWST} Advanced…

PhotoIFU: NIRCam as a Photometric Integral Field Unit for Mapping Feedback in Galaxies

Yongda Zhu, Marcia J. Rieke, Courtney Carreira +25

We present PhotoIFU, a workflow that uses deep multi-band imaging as a low-resolution photometric integral field unit. Applied to PSF-matched JWST/NIRCam imaging, PhotoIFU treats e…

Optical observations of candidate host galaxies of eight fast X-ray transients

Agnes P. C. van Hoof, Peter G. Jonker, Lieke Tommel +15

Fast X-ray transients (FXTs) are extragalactic flashes of X-rays with a typical duration of minutes to hours for which a variety of origins has been proposed and observed. To decip…

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…

High-Resolution ALMA Imaging for a Gravitationally-lensed Quasar at : Constraining the AGN Contribution to Galactic-Scale Dust Heating

Minghao Yue, Xiaohui Fan, Anna-Christina Eilers +6

We present high-resolution (beam size $0\farcs076\times0\farcs040$) Atacama Large Millimeter/submillimeter Array (ALMA) observations of the far-infrared $(λ_\text{rest}=162.7μ\rm{m…

Discovery of Quasar Variability and Early Accretion Disk Signatures at Cosmic Dawn

Gene C. K. Leung, Anna-Christina Eilers, Christos Panagiotou +12

In the nearby universe, quasars are well known to exhibit variability in their brightness over time, offering a powerful tool to probe the physics of accretion onto the SMBH and di…

A Close Quasar Pair in a Massive Galaxy Merger at

Minghao Yue, Xiaohui Fan, Anna-Christina Eilers +3

Close quasar pairs are rare products of galaxy mergers in which both supermassive black holes (SMBHs) are actively accreting, offering strong constraints on merger-driven active ga…

Early metal-enriched baryon cycling before the midpoint of cosmic reionization

Yongda Zhu, Zhiyuan Ji, George D. Becker +13

Models predict that chemical enrichment and gas redistribution should begin rapidly once star formation starts, but direct constraints at the earliest epochs have been scarce. Here…
