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 Transition Region between Brightest Cluster Galaxies and Intra-Cluster Light in Galaxy Groups and Clusters
E. Contini, H. Z. Chen, Q. S. Gu
We take advantage of a state-of-art semi analytic model of galaxy formation, and the model presented in \citet{contini21a}, to investigate the mass distribution of Brightest Cluste…
