Can Blue UV-Bright Galaxies Drive Reionization at Cosmic Dawn? An Galaxy with at

Yunjing Wu, Sijia Cai, Yongda Zhu +28

We revisit EBG-1, a gravitationally lensed galaxy at , using newly obtained deep (14 hr) JWST/NIRSpec G235M () spectroscopy. EBG-1 is one of the bluest gala…

LATED: JWST integral field spectroscopy of a galaxy caught in chemical infancy at behind Abell 2744

Mingyu Li, Roberto Maiolino, Zheng Cai +26

When Population III (Pop III) star formation ended remains an open question. LATED-1 is an intrinsically faint () Ly emitter at revealed by VLT/MU…

LATED: Ly-anchored photometric selection of candidate metal-free and extremely metal-poor star formation from the end of reionisation to cosmic noon

Mingyu Li, Zheng Cai, Roberto Maiolino +24

Cosmological simulations allow a low-level tail of Population III (Pop III) star formation to persist to . Spectroscopic confirmation is expensive, so an efficient photometr…

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…

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…

A massive barred spiral galaxy at z = 5.102 discovered by JWST

Xiaohan Wang, Fengwu Sun, Yoshihisa Asada +21

We report M1149-BSG-z5, a barred spiral galaxy at , identified in the parallel field of MACS J1149+2223 with JWST and HST. M1149-BSG-z5 is the highest redshift barred ga…

A Post-starburst Galaxy Undergoing Ram-pressure Stripping at Redshift 3.06

Mingyu Li, Zheng Cai, Bjorn H. C. Emonts +16

Understanding how galaxies ignite and extinguish their star formation remains a cornerstone question in modern astrophysics. Recent JWST surveys have revealed an overabundance of m…

Early Emergence of Environmental Effects: Accelerated Galaxy Assembly in a z=2.96 Protocluster in the COSMOS Field

Shuaiyi Li, Zheng Cai, Yunjing Wu +4

The redshift range z=2-4 marks a critical transition in large scale structure formation, where the dynamically unrelaxed progenitors of local massive clusters undergo rapid stellar…

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…

Pre-Virialized Assembly at Cosmic Dawn: The Dynamics and Extreme Ionization of Compact Group CGG-z7 at

Xiaoyang Wei, Zheng Cai, Fujiang Yu +2

We report the discovery of CGG-z7, the most compact galaxy group at identified to the north of the GOODS-North field, observed by the JWST POPPIES program. The system c…

Clustering of z~6.6 Quasars and [O III] Emitters Constrains Host Halo Masses and Duty Cycles in 25 ASPIRE Fields

Jiamu Huang, Joseph Hennawi, Elia Pizzati +21

We use data from the JWST ASPIRE Wide Field Slitless Spectroscopy (WFSS) program to measure the auto-correlation function of [O,{\sc iii}] emitters at 5.37.0 and the quasar--[…

Deeper detection limits in astronomical imaging using self-supervised spatiotemporal denoising

Yuduo Guo, Hao Zhang, Mingyu Li +10

The detection limit of astronomical imaging observations is limited by several noise sources. Some of that noise is correlated between neighbouring image pixels and exposures, so i…

ASPIRE: The Environments and Dark Matter Halos of Luminous Quasars in the Epoch of Reionization

Feige Wang, Jaclyn B. Champagne, Jiamu Huang +42

We present a systematic study of the environments of 25 luminous quasars at from the ASPIRE program. Using JWST/NIRCam WFSS data, we identified 487 galaxies at $5.3 \less…
