Reduced incidence of little red dots at z < 3 based on number density and halo mass evolution

Chenxuan Zhang, Huanian Zhang, Qingwen Wu +2

An intriguing puzzle in extragalactic astronomy is the scarcity of Little Red Dots (LRDs) at , compared to their higher abundance at earlier cosmic epochs. To investigate th…

Migration Traps as Variability Attractors. I. 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…
