AEON-z5: A Candidate AGN-driven Outflow Enriching the Circumgalactic Medium at
Xiaoyang Wei, Zheng Cai, Shiwu Zhang +6
The dispersal of chemically enriched gas from galaxies into their surroundings is a key process in galaxy evolution, yet direct observational evidence at z>5 remains scarce. We pre…
First-star imprints in a metal-poor galaxy overdensity near the end of reionization
Zihao Li, Koki Kakiichi, Lise Christensen +24
The first generation of stars, known as Population III (Pop III), formed from primordial gas consisting solely of hydrogen and helium and is believed to have emerged only a few hun…
Constraining the nature of active galactic nuclei through circumgalactic Lya emission at z=2-3
Shiwu Zhang, Zheng Cai, Fabrizio Arrigoni Battaia +8
We present a comprehensive analysis of circumgalactic Lya nebulae around 59 unobscured and 26 obscured quasars at z=2-3, observed with the Keck Cosmic Web Imager (KCWI), to constra…
