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 Strongly Lensed Ultra-faint Arc at with an F200W excess in Abell S1063
Fujiang Yu, Mingyu Li, Zheng Cai +4
Strong gravitational lensing provides a powerful route to probing intrinsically faint galaxies during the first few hundred million years of cosmic history. In this Letter, we repo…
Migration Traps as Variability Attractors: Optical/UV Signatures of Embedded Stellar-Mass Black Holes in Active Galactic Nucleus Disks
Jing-Tong Xing, Tong Liu, Mouyuan Sun +5
We investigate whether embedded stellar-mass black holes (sBHs) in active galactic nucleus (AGN) disks can leave observable optical/UV variability signatures through migration-trap…
Little Red Dots as Supermassive Counterparts of SS 433: A Hyper-Eddington Accretion Framework
Shuying Zhou, Mouyuan Sun, Xihan Ji +11
High-redshift little red dots (LRDs) are compact sources characterized by V-shaped spectral energy distributions (SEDs), broad emission lines, and often prominent Balmer breaks. Th…
Introduction to the Chinese Space Station Survey Telescope (CSST)
CSST Collaboration, Yan Gong, Haitao Miao +119
The Chinese Space Station Survey Telescope (CSST) is an upcoming Stage-IV sky survey telescope, distinguished by its large field of view (FoV), high image quality, and multi-band o…
Characterizing the assembly of dark matter halos with protohalo size histories: I. Redshift evolution, relation to descendant halos, and halo assembly bias
Kai Wang, H. J. Mo, Yangyao Chen +5
We propose a novel method to quantify the assembly histories of dark matter halos with the redshift evolution of the mass-weighted spatial variance of their progenitor halos, i.e.…
