Understand
Recent observations have revealed the structural properties of the dark and luminous mass distribution in spirals.
- These results led to the vision of a new and amazing scenario.
- The investigation of single and coadded objects has shown that the rotation curves of spirals follow, from their centers out to their virial radii, an universal profile that implies a tuned combination of their stellar disk and dark halo mass distributions.
- This, alongside with accurate mass modeling of individual galaxies, poses important challenges to the presently theoretically favored $\Lambda$CDM Cosmology.
