Here, we will review the complex but well-ordered scenario of the properties of the dark halos also in relation with those of the baryonic components they host.

Two-component mass models, consisting of an exponential disk and a spherical halo, are constructed to fit a newly determined rotation curve of NGC 3198 that extends to 11 disk scale lengths.

A&A 192:117van der Kruit PC, Freeman KC (2011) Galaxy disks. Therefore, for galaxies having Note, however, that this is not entirely true for NGC 1090, in which for some radii the Ha lie ∼10 km sOxford University Press is a department of the University of Oxford.

Since observations of galaxy rotation do not match the distribution expected from application of Kepler's laws, they do not match the distribution of luminous matter.A popular interpretation of these observations is that about 26% of the mass of the Universe is composed of dark matter, a Many cosmologists strive to understand the nature and the history of these ubiquitous dark haloes by investigating the properties of the galaxies they contain (i.e. V. HI rotation curve shapes and the Tully–Fisher relations. AJ 136:2761Oh S-H, Brook C, Governato F (2011) Dark and luminous matter in THINGS dwarf galaxies.

MNRAS 454:1161I thank Francesca Matteucci for motivating me towards the enterprise of writing this review.

The distribution of the non-luminous matter in galaxies of different luminosity and Hubble type is much more than a proof of the existence of dark particles governing the structures of the Universe. According to modern models of physical cosmology, a dark matter halo is a basic unit of cosmological structure.
