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…

On the correlation between Ly forest opacity and galaxy density in late reionization models

Nakul Gangolli, Anson D'Aloisio, Christopher Cain +2

The relationship between Ly forest opacity and local galaxy density (the opacity-density relation) is a key observational test of late reionization models. Using narrow-band sur…

Quantifying Lyman- emissions from reionization fronts

Bayu Wilson, Anson D'Aloisio, Christopher Cain +2

During reionization, intergalactic ionization fronts (I-fronts) are sources of Ly line radiation produced by collisional excitation of hydrogen atoms within the fronts. In princ…

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…

A Community Science Case for E-ELT HIRES

R. Maiolino, M. Haehnelt, M. T. Murphy +57

Building on the experience of the high-resolution community with the suite of VLT high-resolution spectrographs, which has been tremendously successful, we outline here the (scienc…
