We use a homogeneous sample of about 1100 rotation curves (RCs) and relative surface photometry to investigate (out to 2 optical radii and over 6 mag) the main mass structure properties of spirals. We confirm the strong dependence on luminosity for both the profile and the amplitude of RCs. Spiral RCs show the striking feature that a single parameter, the luminosity, dictates the rotation velocity at any radius for all objects, so revealing the existence of a universal RC. At high luminosity, there is a slight discrepancy between the profiles of RCs and those predicted from the luminous matter (LM) distributions: this implies a small, yet detectable, amount of dark matter (DM). At low luminosities the failure of the LM prediction is most severe, and DM is the only relevant mass component. Some of the derived scaling properties between dark and luminous galactic structure parameters are: (a) the DM/LM mass ratio at the optical radius scales inversely with luminosity; (b) the halo core radius is comparable to the optical radius, but shrinks for lower luminosities; (c) the central halo density scales as L^{-0.7}; (d) the halo virial mass scales as L^{0.5}. Such scaling properties can be represented as a curve in the luminosity-(DM/LM ratio)-(DM core radius)-(central DM density) space, which acts as the spirals' counterpart to the FP of ellipticals.

Satellite compaction pathways: environmental drivers shaping dwarf galaxy corpulence in the TNG50 simulation
In TNG50, compact dwarf satellites (log M_star 8.4-9.2) form via DM-rich gas inflows in low-merger environments, tidal stripping for DM-poor cases, and ram-pressure starbursts for some metal-rich ones.
