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…
The Correlation of Star Formation Quenching with Internal Galaxy Properties and Environment
Taysun Kimm, Rachel S. Somerville, Sukyoung K. Yi +8
We investigate the correlation of star formation quenching with internal galaxy properties and large scale environment (halo mass) in empirical data and theoretical models. We make…
Are Brightest Halo Galaxies Central Galaxies?
Ramin A. Skibba, Frank C. van den Bosch, Xiaohu Yang +3
It is generally assumed that the central galaxy in a dark matter halo, that is, the galaxy with the lowest specific potential energy, is also the brightest halo galaxy (BHG), and t…
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…
Constraints on circum-galactic media from Sunyaev-Zel'dovich effects and X-ray data
Xuanyi Wu, Houjun Mo, Cheng Li +1
We use observational measurements of thermal and kinetic Sunyaev-Zel'dovich effects, as well as soft X-ray emission associated with galaxy groups to constrain the gas density and t…
