The Structure of Dark Matter Haloes in Dwarf Galaxies [PDF]
, 1995 Recent observations indicate that dark matter haloes have flat central density profiles. Cosmological simulations with non-baryonic dark matter predict however self similar haloes with central density cusps.

Dark matter halo concentrations in the Wilkinson Microwave Anisotropy Probe year 5 cosmology [PDF]
, 2008 We use a combination of three large N-body simulations to investigate the dependence of dark matter halo concentrations on halo mass and redshift in the Wilkinson Microwave Anisotropy Probe year 5 (WMAP5) cosmology.

Imprints of flavor anomalies on neutrino oscillations through dark matter halo
Nuclear Physics B, 2023 In this work we study the impact of new physics, stimulated by flavor anomalies, on neutrino oscillations through dense dark matter halo. Inspired by a model where a Majorana dark matter fermion and two new scalar fields contribute to b→sμ+μ− transition ...

Estimating the dark matter halo mass of our Milky Way using dynamical tracers [PDF]
, 2015 The mass of the dark matter halo of the Milky Way can be estimated by fitting analytical models to the phase-space distribution of dynamical tracers.

The Astrophysical Journal, 2004 We study properties of dark matter halos at high redshifts z=2-10 for a vast range of masses with the emphasis on dwarf halos with masses 10^7-10^9 Msun/h. We find that the density profiles of relaxed dwarf halos are well fitted by the NFW profile and do not have cores. We compute the halo mass function and the halo spin parameter distribution and find

Recoiling black holes in static and evolving dark matter halo potential [PDF]
Serbian Astronomical Journal, 2015 We follow trajectories of kicked black holes in static and evolving dark matter halo potential. We explore both NFW and Einasto dark matter density distributions.

The link between the assembly of the inner dark matter halo and the angular momentum evolution of galaxies in the EAGLE simulation [PDF]
, 2015 We explore the co-evolution of the specific angular momentum of dark matter haloes and the cold baryons that comprise the galaxies within. We study over 2000 galaxies within the reference cosmological hydrodynamical simulation of the ‘Evolution and ...

Dark matter annihilation at the galactic center [PDF]
, 1999 If cold dark matter is present at the galactic center, as in current models of the dark halo, it is accreted by the central black hole into a dense spike.
