Accurate determination of halo velocity bias in simulations and its cosmological implications
Junde Chen, Pengjie Zhang, Yi Zheng +2
A long-standing issue in peculiar velocity cosmology is whether the halo/galaxy velocity bias at large scale. The resolution of this important issue must resort to high pre…
