Spherically Symmetric Fluid Simulations of Black Hole Accretion in Self-Interacting Dark Matter Halos
Zhe Meng, Tan Chen, Bocheng Zhu +4
We investigate black hole accretion in self-interacting dark matter (SIDM) halos using a self-gravitating fluid model with thermal conduction. We develop a robust one-dimensional s…
Cosmological Simulation with Population III Stellar Feedback and Metal Enrichment I: Model Description And Convergence Test
Bocheng Zhu, Liang Gao
We present SPARK (Simulation of Pop III in Arepo with Radiation and Kinetic feedback) framework, a new Pop III + Pop II subgrid framework implemented in the moving-mesh code {\sc a…
APOSTLE vs. AURIGA Simulations: How Subgrid Models Shape Milky Way Analogs
Jianhong Hu, Hang Yang, Liang Gao
Despite significant progress in cosmological simulations of galaxy formation, the role of subgrid physics in shaping the detailed properties of galaxies remains incompletely unders…
The capture of halo material by orbiting subhaloes
Hang Yang, Simon D. M. White, Liang Gao
When a dark matter halo falls into a more massive object and becomes a subhalo, it typically loses much of its mass through tidal stripping. The reverse process is also possible in…
Where are the Population III star relics in the simulated Milky Way analogues?
Hang Yang, Liang Gao, Qi Guo +3
Using 6 Milky Way analogues with two different numerical resolutions from the Auriga simulation, we investigate the total mass, spatial distribution and kinematics of the Populatio…
The Impact of Local Stellar Radiation on Dwarf Galaxy Formation Around Milky Way Analogues Across Cosmic Reionization
Bocheng Zhu, Liang Gao
We explore the effect of local stellar radiation on the formation and evolution of dwarf galaxies around Milky Way (MW) analogues. Using five simulations from the Auriga project, b…
