A Bending in the Size-mass Relation of Star-forming Galaxies across at a Critical Stellar Mass of Revealed by JWST
Longyue Chen, Tao Wang, Hanwen Sun +12
We investigate the rest-frame optical size-stellar mass relation of galaxies at using deep JWST/NIRCam and MIRI imaging from the PRIMER survey. We find that star-formin…
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…
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…
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…
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…
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…
