Cusps, cores, and one acceleration: dark-matter haloes versus modified dynamics across the full SPARC sample

The rotation curves of the 175 disk galaxies in the SPARC database are confronted, one by one and under identical conditions, with the two mass models that have dominated the missing-mass debate for four decades: a cold dark-matter halo of Navarro–Frenk–White (NFW) form, and Milg...
