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…
Misaligned or chaotic? A strong break of axial symmetry in the local LRD J1025 revealed with VLT/FORS2 spectropolarimetry
Francesco D'Eugenio, Gabriele Pezzulli, Roberto Maiolino +18
Little Red Dots (LRDs) are compact active galactic nuclei (AGN) with unusual spectral energy distributions and broad Balmer emission, candidate signposts of rapid black-hole growth…
A Compact Proto-group at : A Massive Galaxy Caught in Formation
Ronaldo Laishram, Yusei Koyama, Fengwu Sun +11
The authors report the discovery of a compact galaxy proto‑group at redshift ~5, confirming six members spectroscopically and measuring their stellar masses, star‑formation propert…
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…
Little red dots as a cosmological probe: constraining with quasi-periodic pulsations
Zijian Zhang, Kohei Inayoshi, Masamune Oguri +4
The James Webb Space Telescope (JWST) has uncovered a population of ``little red dots'' (LRDs) at , potentially representing early supermassive black holes embedded in…
A Steep-Extinction QSO at z=4.6: JWST Evidence for Abundant Small Dust Grains
Mingyu Li, Zheng Cai, Roberto Maiolino +9
The rapid accumulation of massive dust reservoirs in the early Universe remains a major challenge in astrophysics. While core-collapse supernovae can inject large dust grains ($a \…
