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_{…
From filaments to clumps: filament properties with synthetic Herschel observations
Zhen-Xing Ma, Zu-Jia Lu
Systematic surveys of filaments have been conducted to study their properties and their relationship to the process of star formation. In this paper, we use synthetic Herschel obse…
The Way We Tally Becomes the Tale: the Impact of Selection Strategies on the Inferred Evolution of Little Red Dots Across Cosmic Time
Pierluigi Rinaldi, Kevin Hainline, Francesco D'Eugenio +27
Little Red Dots (LRDs) have emerged as a key population linked to early black hole growth, yet photometric selections have predominantly targeted only the most extreme red systems,…
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…
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…
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…
