Testing dark matter distributions by neutrino–dark matter interactions [PDF]
The European Physical Journal C, 2020 AbstractAt present, a variety of dark matter (DM) density profiles are available in the literature, able to fit the observed rotation velocity curves in galaxies. These distributions may be classified according to nature and mass of the DM candidate, and their estimation of the concentration of DM on halo scales, as well as through their central ...

Distribution function of dark matter [PDF]
Physical Review D, 2006 There is good evidence from N-body simulations that the velocity distribution in the outer parts of halos is radially anisotropic, with the kinetic energy in the radial direction roughly equal to the sum of that in the two tangential directions. We provide a simple algorithm to generate such cosmologically important distribution functions.

Sources and distributions of dark matter [PDF]
Nuclear Physics B - Proceedings Supplements, 1995 In the first section, I will try to convey a sense of the variety of observational inputs that tell us about the existence and the spatial distribution of dark matter in the universe. In the second section, I will briefly review the four main dark matter candidates, taking note of each candidate's status in the world of particle physics, its production

The dark matter distribution in disc galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We use high-quality optical rotation curves of 9 low-luminosity disk galaxies to obtain the velocity profile of the surrounding dark matter halos. We find that they increase linearly with radius at least out to the stellar disk edge, implying that, over the entire region where the stars reside, the density of the dark halo is constant.

DISTRIBUTION FUNCTION OF DARK MATTER WITH CONSTANT ANISOTROPY [PDF]
International Journal of Modern Physics D, 2008 N-body simulations of dark matter halos show that the density is cusped near the center of the halo. The density profile behaves as r–γ in the inner parts, where γ ≃ 1 for the NFW model and γ ≃ 1.5 for the Moore model, but in the outer parts the two models agree with each other in the asymptotic behavior of the density profile.

THE DISTRIBUTION OF DARK MATTER IN THE MILKY WAY’S DISK [PDF]
The Astrophysical Journal, 2014 We present an analysis of the effects of dissipational baryonic physics on the local dark matter (DM) distribution at the location of the Sun, with an emphasis on the consequences for direct detection experiments. Our work is based on a comparative analysis of two cosmological simulations of a Milky Way halo: Eris, a full hydrodynamic simulation, and ...
