Exploring the signature of assembly bias and modified gravity using small-scale clusterings of galaxies
Using mock galaxy catalogs, the authors show that a single halo velocity bias parameter can recover cosmological parameters when assembly bias is modeled, and that it deviates from unity for strong modified gravity models.
