The halo concentration and mass relation traced by satellite galaxies
Qing Gu, Qi Guo, Tianchi Zhang +3
We study the relation between halo concentration and mass (c-M relation) using the Seventh and Eighth Data Release of the Sloan Digital Sky Survey (SDSS DR7 and DR8) galaxy catalog…
The spatial distribution of satellites in galaxy clusters
Qing Gu, Qi Guo, Tianchi Zhang +4
The planar distributions of satellite galaxies around the Milky Way and Andromeda have been extensively studied as potential challenges to the standard cosmological model. Using th…
The role of mergers and gas accretion in black hole growth and galaxy evolution
TianChi Zhang, Qi Guo, Yan Qu +1
We use a semi-analytic galaxy formation model to study the co-evolution of supermassive black holes (SMBHs) with their host galaxies. Although the coalescence of SMBHs is not impor…
Galaxy properties in the cosmic web of EAGLE simulation
Wenxiao Xu, Qi Guo, Haonan Zheng +8
We investigate the dependence of the galaxy properties on cosmic web environments using the most up-to-date hydrodynamic simulation: Evolution and Assembly of Galaxies and their En…
