lambda cold dark matter
Rotation curves as evidence of a dark matter halo. The presence of dark matter DM in the halo is inferred from its gravitational effect on a spiral galaxys rotation curveWithout large amounts of mass throughout the roughly spherical halo the rotational velocity of the galaxy would decrease at large distances from the galactic center just as the orbital speeds of the outer planets.

The existence of non-baryonic cold dark matter CDM is today a major feature of the Lambda-CDM model that describes the cosmology of the universe.
. Newtons version of Keplers Third Law implies that the. In order to accommodate a flat rotation curve a density profile for a galaxy and its environs must be different than one that is centrally concentrated. Il modello Lambda-CDM o ΛCDM CDM sta per Cold Dark Matter ossia Materia Oscura Fredda è un modello che riproduce in modo soddisfacente le osservazioni della cosmologia del Big Bang spiegando in particolare le osservazioni della radiazione cosmica di fondo CMB della struttura a grande scala delluniverso e delle supernovae che indicano un universo in espansione accelerata.
