Based on the DECaLS shear catalog, we study the scaling relations between halo mass ( M h ) and various proxies for Sloan Digital Sky Survey central galaxies, including stellar mass ( M * ), stellar velocity dispersion ( σ * ), abundance-matching halo mass ( M AM ), and satellite velocity dispersion...
