In the current ACDM cosmological scenario, N-body simulations provide us with a universal mass profile, and consequently a universal equilibrium circular velocity of the virialized objects, as galaxies. In this paper we obtain, by combining kinematical data of their inner regions with global observational properties, the universal rotation curve of disc galaxies and the corresponding mass distribution out to their virial radius. This curve extends the results of Paper I, concerning the inner luminous regions of Sb-Im spirals, out to the edge of the galaxy haloes.

GHASP: an Hα kinematic survey of spiral and irregular galaxies – V. Dark matter distribution in 36 nearby spiral galaxies (2007, result): “Salucci et al. 2007 also get such a relation between the central density and the core radius of the halo (see Figure 1 of their paper) although for a different fitting model.”
Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions (2011, background): “This is precisely what is observed (Figure 15), and is in accordance [163] with the more complex empirical parametrization of observed rotation curves that has been proposed in [377].”

Constraints on star formation driven galaxy winds from the mass–metallicity relation at z= 0 (2010, result): “…with the more recent calibrations by Pizagno et al. (2007), as long as the dynamical contribution of the dark matter within a few optical radii is less than the onepredicted by a pure Navarro, Frenk, & White (1996) mass profile, in line with many other studies (e.g., Salucci et al. 2007).”
KINEMATICAL AND CHEMICAL VERTICAL STRUCTURE OF THE GALACTIC THICK DISK. II. A LACK OF DARK MATTER IN THE SOLAR NEIGHBORHOOD, (2012, background): “…sets of indices have been proposed in the literature, suggesting either “cuspy” (e.g., Navarro et al. 1997; Moore et al. 1999; Binney & Evans 2001; Ludlow et al. 2009) or “cored” profiles (e.g., de Boer et al. 2005; Narayan et al. 2005; Gentile et al. 2007; Salucci et al. 2007; Oh et al. 2008).”
A constant dark matter halo surface density in galaxies (2009, methodology): “By χ2 fitting the URC with a Burkert halo + a Freeman disk velocity model, with no assumptions on the amount of baryonic matter, we obtain ρ0 and r0 as the best-fit values (see equations 6a, 7 and 10 of Salucci et al., 2007).”
Non-linear evolution of cosmological structures in warm dark matter models (2011, background): “…2004; Springel et al. 2008; Stadel et al. 2009), whereas the density profiles inferred from galaxy rotation curves are significantly shallower (Moore et al. 1999) (and for recent studies see Swaters et al. 2003; Salucci et al. 2007; de Blok et al. 2008; Gentile et al. 2009 and references therein).”
