英文摘要We derive the mass-weighted total density slopes within the effective (half-light) radius, gamma ', for more than 2000 nearby galaxies from the SDSS-IV (Sloan Digital Sky Survey IV) MaNGA survey using Jeans-anisotropic-models applied to integral field unit observations. Our galaxies span a wide range of the stellar mass (10(9) M-circle dot < M-* < 10(12) M-circle dot) and the velocity dispersion (30 km s(-1) < sigma(upsilon) < 300 km s(-1)). We find that for galaxies with velocity dispersion sigma(upsilon) > 100 km s(-1), the density slope has a mean value (gamma ') = 2.24 and a dispersion sigma(gamma) = 0.22, almost independent of velocity dispersion, consistent with previous lensing and stellar dynamical analysis. We also quantitatively confirm with high accuracy a turnover in the gamma ' - sigma(upsilon) relation is present at a 100 km s-1, below which the density slope decreases rapidly with sigma(upsilon), consistent with the results reported by previous analysis of ATLAS(3D) survey. Our analysis shows that a large fraction of dwarf galaxies (below M-* = 10(10) M-circle dot) have total density slopes shallower than I, which implies that they may reside in cold dark matter haloes with shallow density slopes. We compare our results with that of galaxies in hydrodynamical simulations of EAGLE, Illustris, and IllustrisTNG projects, and find all simulations predict shallower density slopes for massive galaxies with high sigma(upsilon). Finally, we explore the dependence of gamma ' on the positions of galaxies in haloes, namely centrals versus satellites, and find that for the same velocity dispersion, the amplitude of gamma ' is higher for satellite galaxies by about 0.1.
