Interpreting the strong clustering of ultra-diffuse galaxies by halo spin bias
Qinglin Ma, Cheng Li, Yangyao Chen +1
We use the IllustrisTNG300-ODM simulation to investigate the spin bias of low-mass halos and its connection to the strong clustering of ultra-diffuse galaxies (UDGs) reported by Zh…
Radio AGN feedback sustains quiescence only in a minority of massive galaxies
Huiling Liu, Yan Lu, Hui Hong +11
Radio active galactic nuclei (AGNs) eject a huge amount of energy into the surrounding medium and are thought to potentially prevent gas cooling and maintain the quiescence of mass…
Two-phase formation of galaxies: the coevolution between galaxies and dark matter halos
Qinglin Ma, Yangyao Chen, Houjun Mo
We use FIRE-2 cosmological zoom-in hydrodynamic simulations to investigate the co-evolution between Milky Way-size galaxies and their host dark matter halos. We find that the forma…
A two-phase model of galaxy formation: IV. Seeding and growing supermassive black holes in dark matter halos
Yangyao Chen, Houjun Mo, Huiyuan Wang
We present a theoretical framework for seeding and growing supermassive black holes (SMBHs) in dark matter halos along their assembly histories. Seeds are bred out of Pop-III stars…
The Bigfoot: A footprint of a Coma cluster progenitor at z=3.98
Hanwen Sun, Tao Wang, Emanuele Daddi +13
Protoclusters, galaxy clusters' high redshift progenitors, hold the keys to understanding the formation and evolution of clusters and their member galaxies. However, their cosmolog…
Unexpected clustering pattern in dwarf galaxies challenges formation models
Ziwen Zhang, Yangyao Chen, Yu Rong +4
The galaxy correlation function serves as a fundamental tool for studying cosmology, galaxy formation, and the nature of dark matter. It is well established that more massive, redd…
