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…

Can high-redshift AGN observed by JWST explain the EDGES absorption signal?

Alexandra Nelander, Christopher Cain, Jordan C J DSilva +3

The Experiment to Detect the Global Epoch of Reionization 21 cm Signal (EDGES) has reported evidence for an absorption feature in the sky-averaged radio background near 78 MHz. A c…

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…

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…

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…

Towards an accurate treatment of the reduced speed of light approximation in parameterized radiative transfer simulations of reionization

Christopher Cain

The reduced speed of light approximation (RSLA) has been employed to speed up radiative transfer simulations of reionization by a factor of . However, it has been sho…
