Low Ly Visibility in Galaxy Overdensities: Reionization Topology and Neutral-Fraction Ceilings from DIVER over
Yongda Zhu, Xiaohui Fan, Laura C. Keating +19
Ly-alpha emission is widely used to trace cosmic reionization, but its interpretation depends on how Ly-alpha visibility varies with galaxy environment. We use deep JWST/NIRSpec ob…
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…
A quasar hatching from a buried red phase at z = 3.7
Zheng Ma, Yongda Zhu, Zhiyuan Ji +21
We present JADES-GS 209777, previously cataloged as CANDELS J033238.02-274626.2, hereafter "the Hatchling," a red quasar at . While the source has been reported in earlier…
An (in)complete NIRSpec census of Balmer absorption in Type 1 AGN -- radiation-driven outflows in little red dots, quasars and variable stars
Ignas Juodžbalis, Xihan Ji, Francesco D'Eugenio +17
A notable achievement of the first generation of JWST surveys was the discovery of an abundance of faint high-redshift () broad-line active galactic nuclei (AGN) in the $L_{…
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…
Clumps in High-Redshift Galaxies: Mass Scaling and Radial Trends from JADES
Yongda Zhu, Marcia J. Rieke, Zhiyuan Ji +20
Massive star-forming clumps are a prominent feature of high-redshift galaxies and are thought to trace gravitational fragmentation, feedback, and bulge growth in gas-rich disks. We…
Undermassive Hosts of AGN from JWST/NIRCam Image Decomposition with CONGRESS, FRESCO, and JADES
Zheng Ma, Eichi Egami, Yongda Zhu +18
In the local Universe, supermassive black hole (SMBH) masses strongly correlate with their host-galaxies' stellar masses (), but galaxies hosting faint AGN recently found by…
Quasar Radiative Feedback May Suppress Galaxy Growth on Intergalactic Scales at
Yongda Zhu, Eiichi Egami, Xiaohui Fan +27
We present observational evidence that intense ionizing radiation from a luminous quasar suppresses nebular emission in nearby galaxies on intergalactic scales at . Using JW…
The Large-scale Environments of Low-luminosity AGNs at and Implications for Their Host Dark Matter Halos from a Complete NIRCam Grism Redshift Survey
Xiaojing Lin, Xiaohui Fan, Fengwu Sun +19
We study the large-scale environments and clustering properties of 28 low-luminosity AGNs at in the GOODS-N field. Our sample, identified from the JWST NIRCam Imaging and…
Abundant Population of Broad H Emitters in the GOODS-N Field Revealed by CONGRESS, FRESCO, and JADES
Junyu Zhang, Eiichi Egami, Fengwu Sun +15
We present a spectroscopic search for broad H emitters at z3.7-6.5 in the GOODS-N field, utilizing JWST/NIRCam slitless spectroscopy from FRESCO and CONGRESS, complemen…
The First Photometric Evidence of a Transient/Variable Source at z>5 with JWST
Christa DeCoursey, Eiichi Egami, Fengwu Sun +27
The James Webb Space Telescope (JWST) discovered 79 transients out to 4.8 through the JADES Transient Survey (JTS), but the JTS did not find any 5 transients. Here,…
The Luminosity Function and Clustering of H Emitting Galaxies at from a Complete NIRCam Grism Redshift Survey
Xiaojing Lin, Eiichi Egami, Fengwu Sun +20
We study the luminosity function (LF) and clustering properties of 888 H emitters (HAEs) at in the GOODS-N field. The sample, built from JWST CONGRESS and FRESCO…
Slitless Areal Pure-Parallel HIgh-Redshift Emission Survey (SAPPHIRES): Early Data Release of Deep JWST/NIRCam Images and Spectra in MACS J0416 Parallel Field
Fengwu Sun, Yoshinobu Fudamoto, Xiaojing Lin +25
We present the early data release (EDR) of SAPPHIRES, a JWST Cycle-3 Treasury imaging and spectroscopic survey using the powerful NIRCam wide-field slitless spectroscopic (WFSS) mo…
An Investigation Into The Selection and Colors of Little Red Dots and Active Galactic Nuclei
Kevin N. Hainline, Roberto Maiolino, Ignas Juodzbalis +25

SMILES: Potentially Higher Ionizing Photon Production Efficiency in Overdense Regions
Yongda Zhu, Stacey Alberts, Jianwei Lyu +14
The topology of reionization and the environments where galaxies efficiently produce ionizing photons are key open questions. For the first time, we investigate the trend between i…
