White dwarfs and Galactic dark matter [PDF]

open access: yes, 2002
We discuss the recent discovery by Oppenheimer et al (2001) of old, cool white dwarf stars, which may be the first direct detection of Galactic halo dark matter.

Dark matter annihilation at the galactic center [PDF]

open access: yes, 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.

Dynamical Models of Spherical Galaxies with Massive Halo [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2003
Using the Schwarzschild's linear programming technique, we obtained the general solutions of the collisionless Bolzmann equation describing the spherical galaxy in dynamical equilibrium.

Small scale structures in coupled scalar field dark matter

open access: yesPhysics Letters B, 2014
We investigate structure formation for ultra-light scalar field dark matter coupled to quintessence, in particular the cosmon–bolon system. The linear power spectrum is computed by a numerical solution of the coupled field equations.

Splashback Radius in a Spherical Collapse Model

open access: yesUniverse, 2022
It was shown several years ago that dark matter halo outskirts are characterized by very steep density profiles in a very small radial range. This feature has been interpreted as a pile-up of different particle orbits at a similar location, namely ...

Dwarf Dark Matter Halos

open access: yesThe 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
