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…
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…
Compact Core, Extended Reach: A Bipolar kpc-Scale Elongation in a Little Red Dot at
Zhiyuan Ji, Yang Sun, Mauro Giavalisco +7
Little Red Dots (LRDs) appear extremely compact at rest-frame optical wavelengths, yet many show extended rest-frame UV morphology revealing more complex internal structure. We pre…
Through the Veil: Ly Illuminates the Host Galaxies of Little Red Dots
Zhiyuan Ji, Yang Sun, Mauro Giavalisco +5
Little Red Dots (LRDs) are enigmatic, compact red sources ubiquitous in JWST deep fields whose physical nature remains elusive. As one of the most sensitive tracers of neutral hydr…
