Exploring the signature of assembly bias and modified gravity using small-scale clusterings of galaxies
Yirong Wang, Zhongxu Zhai, Xiaohu Yang +1
We apply a halo velocity bias model, , within the Aemulus simulation suite for General Relativity (GR) to investigate its efficacy in identifying the signature of assembly…
