An emerging baryon cycle in a galaxy 500 million years after the Big Bang
Shengzhe Wang, Xin Wang, Hang Zhou +17
The emergence of stellar feedback as a regulator of galaxy growth marks a fundamental transition in cosmic history. At early times, rapid gas accretion and collapse may induce inte…
Satellite quenching by radio jets of central galaxies in galaxy groups
Yijun Wang, Tao Wang, Dingyi Zhao +9
Feedback from active galactic nuclei (AGN) is now recognized as a key component of galaxy formation models. It plays a central role in regulating the growth and quenching of galaxi…
Super-Eddington accretion of black holes in early nuclear bursts gives birth to Little Red Dots
Yangyao Chen, Houjun Mo
In a recent paper, Chen et al. developed a framework for modeling the seeding and growth of supermassive black holes (BHs) in the context of CDM cosmogony. Here, we use a set of…
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…
