cds-question@unistra.frgalaxy-rotationFor disc galaxies, a close relation exists between the distribution of light and the shape of the rotation curve. We quantify this relation by measuring the inner circular-velocity gradient d_R_V(0) for spiral and irregular galaxies with high-quality rotation curves. We find that d_R_V(0) correlates with the central surface brightness {mu}_0_ over more than two orders of magnitude in d_R_V(0) and four orders of magnitudes in {mu}_0_. This is a scaling relation for disc galaxies. It shows that the central stellar density of a galaxy closely relates to the inner shape of the potential well, also for low-luminosity and low-surface-brightness galaxies that are expected to be dominated by dark matter.2013MNRAS.433L..30Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/433/L30CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/145 : Nearby Galaxies Catalogue (NBG) (Tully 1988)VII/198 : Mark III Catalog of Galaxy Peculiar Velocities (Willick+ 1997)J/AJ/138/332 : LEDA CMD/tip of the red giant branch (Jacobs+, 2009)J/AJ/112/2471 : The Ursa Major cluster.
