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…
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…
Galaxy Underdensities Host the Clearest IGM Ly Transmission and Indicate Anisotropic Reionization
Yongda Zhu, George D. Becker, Anson D'Aloisio +6
How galaxies drive reionization and what governs its geometry remain fundamental questions. We present JWST/NIRCam wide-field slitless spectroscopy (WFSS) observations toward two o…
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…
A Potential Link between Nuclear Winds and Cold Gas Outflows on Kiloparsec Scales in Reionization-Era Quasars
Yongda Zhu, Marcia J. Rieke, Luis C. Ho +23
Feedback from accreting supermassive black holes may regulate galaxy evolution, but statistical evidence linking nuclear winds to kiloparsec-scale cold gas outflows remains limited…
Discovery of a Unique Close Quasar-DSFG Pair Linked by a [C II] Bridge at
Yongda Zhu, Tom J. L. C. Bakx, Ryota Ikeda +11
We report the discovery of a unique quasar-dusty star-forming galaxy (DSFG) system at , consisting of the bright quasar J1133+1603 () and its compact…
Stellar Population Effects on the Inferred Photon Density at Reionization
E. R. Stanway, J. J. Eldridge, G. D. Becker
The relationship between stellar populations and the ionizing flux with which they irradiate their surroundings has profound implications for the evolution of the intergalactic med…
