abstract
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.

Derives an exact solution for a black hole in anisotropic dark sector FLRW background with mass co-evolving via radius-dependent coupling governed by the dark halo profile.
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.
Derives perihelion shift equations for S2 star in generalized Schwarzschild-Dehnen BH-DM spacetime and constrains gamma, rho_s, rs via MCMC on Do et al. and Gillessen et al. datasets.
Neural-network regression reconstructs the semi-visible-jet invisible fraction r_inv more precisely than prior analytical methods in ISR-boosted photon-associated events.
Lattice simulations show that preheating in a Palatini R^2 model with non-minimal coupling fragments the inflaton into oscillons that emit a stochastic gravitational-wave background peaking near 4 GHz.
