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…

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…
