Anisotropic Secondary Bias of Dark Matter Haloes in a CDM Universe
Qinglin Ma, Cheng Li
The paper investigates how the clustering of dark matter haloes depends on halo properties and their orientation relative to the halo’s major axis, using the TNG300-1-Dark simulati…
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…
Galaxy populations in groups and clusters-II. Conditional luminosity functions at redshifts from z~1 to z~0
Ce Gao, Cheng Li, Houjun Mo +5
Using DESI SV3 spectroscopic group centrals and HSC photometric data, we measure conditional luminosity functions (CLFs) of central and satellite galaxies for red and blue populati…
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…
Lopsided and Bulging Distribution of Satellites around Paired Halos. II. 3D Analysis and Dependence on Projection and Selection Effects
Qinglin Ma, Cheng Li, Yanhan Guo
We use the Illustris-TNG simulation to investigate the anisotropic distribution of subhalos in/around dark matter halo pairs. We measure the position angle () of each subhalo b…
Lopsided and Bulging Distribution of Satellites around Paired Halos. I. Observational Measurements and Comparison with Halo-based Models
Yanhan Guo, Qinglin Ma, Cheng Li
We investigate the angular distribution of satellite galaxies in and around pairs of galaxy groups in SDSS and compare the results with the satellite distribution in pairs of dark…
