Halo assembly bias in the early Universe: a clustering probe of the origin of the Little Red Dots
Zihao Wang, Fangzhou Jiang, Haonan Zheng +5
The clustering of galaxies encodes key information about the structure and assembly history of their host dark matter (DM) haloes, providing a powerful probe of the origin of extre…
HIDES -- I. The population and diversity of HI-rich 'dark' galaxies in the Hestia and Auriga simulations
Haonan Zheng, Fangzhou Jiang, Shihong Liao +1
We present our investigation of HI-rich 'Dark' galaxiEs in Simulations (HIDES), specifically using the Hestia and Auriga simulations in this work. We select galaxies that are faint…
Particle loads for cosmological simulations with equal-mass dark matter and baryonic particles
Shihong Liao, Yizhou Liu, Haonan Zheng +5
Traditional cosmological hydrodynamical simulations usually assume equal-numbered but unequal-mass dark matter and baryonic particles, which can lead to spurious collisional heatin…
The impact of cosmic filaments on the abundance of satellite galaxies
Yuxi Meng, Haonan Zheng, Shihong Liao +9
The impact of cosmic web environments on galaxy properties plays a critical role in understanding galaxy formation. Using the state-of-the-art cosmological simulation IllustrisTNG,…
Ultra-diffuse galaxies in the EAGLE simulation
Haonan Zheng, Shihong Liao, Liang Gao +1
We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultra-diffuse galaxies (UDGs). We identify 181 UDGs and find their propert…
Formation of the Little Red Dots from the Core-collapse of Self-interacting Dark Matter Halos
Fangzhou Jiang, Zixiang Jia, Haonan Zheng +5
We present a statistical study of black hole (BH) formation and growth seeded by gravothermal core collapse of self-interacting dark matter (SIDM) halos at high redshift, using a c…
