Dark Matter in galaxies: leads to its Nature

Salucci, Paolo, De Laurentis, Mariafelicia

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.
