Effectiveness of halo and galaxy properties in reducing the scatter in the stellar-to-halo mass relation
Wenxiang Pei, Qi Guo, Shi Shao +2
The stellar-to-halo mass relation (SHMR) is a fundamental relationship between galaxies and their host dark matter haloes. In this study, we examine the scatter in this relation fo…
JWST's first glimpse of a z > 2 forming cluster reveals a top-heavy stellar mass function
Hanwen Sun, Tao Wang, Ke Xu +11
Clusters and their progenitors (protoclusters) at z = 2-4, the peak epoch of star formation, are ideal laboratories to study the formation process of both the clusters themselves a…
A younger Universe implied by satellite pair correlations from SDSS observations of massive galaxy groups
Qing Gu, Qi Guo, Marius Cautun +5
Many of the satellites of galactic-mass systems such as the Miky Way, Andromeda and Centaurus A show evidence of coherent motions to a larger extent than most of the systems predic…
Subhalo abundance and satellite spatial distribution in Milky Way-Andromeda-like paired haloes
Kemeng Li, Shi Shao, Ping He +2
We study the subhalo and satellite populations in haloes similar to the Milky Way (MW)-Andromeda paired configuration in the Millennium II and P-Millennium simulations. We find sub…
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…
