The Connection Between Galaxies and Their Dark Matter Halos [PDF]

Annual Review of Astronomy and Astrophysics, 2018
In our modern understanding of galaxy formation, every galaxy forms within a dark matter halo. The formation and growth of galaxies over time is connected to the growth of the halos in which they form. The advent of large galaxy surveys as well as high-resolution cosmological simulations has provided a new window into the statistical relationship ...

THE SPHERICALIZATION OF DARK MATTER HALOS BY GALAXY DISKS [PDF]

Astrophysical Journal Letters, 2010
Cosmological simulations indicate that cold dark matter (CDM) halos should be triaxial. Verifying observationally this theoretical prediction is, however, less than straightforward because the assembly of galaxies is expected to modify the halo shapes and to render them more axisymmetric.

Galaxy halos and the nature of dark matter

AIP Conference Proceedings, 1995
One of the few observational facts that we know about dark matter is that within about one tenth of the virial radius, the dark halos of some galaxies have density profiles which fall with the radius as ρ(r)∝rn, where n≊0. Any successful dark matter candidate must be able to reproduce these observations.

Dark Matter in the Halo of the Galaxy

2002
We consider a self-gravitating noninteracting fermion gas at nonzero temperature as a model for the dark matter halo of the Galaxy. This fermion gas model is then shown to imply the existence of a supermassive compact dark object at the Galactic center.
