Bose-Einstein condensation of dark matter axions.
We show that cold dark matter axions thermalize and form a Bose-Einstein condensate (BEC). We obtain the axion state in a homogeneous and isotropic universe, and derive the equations governing small axion perturbations. Because they form a BEC, axions differ from ordinary cold dark matter in the nonlinear regime of structure formation and upon entering the horizon. Axion BEC provides a mechanis...
متن کاملA Numerical Study of Boson Stars: Einstein Equations with a Matter Source
The study of the properties and dynamics of self-gravitating bosonic objects in Einstein gravity was conducted. Bosons are promising candidates for dark matter. They can form compact objects through a Jeans instability mechanism. We studied boson stars made up of self-gravitating scalar fields, with and without nonlinear self-couplings. These are non-topological solutions of the coupled Einstei...
متن کاملRadial velocity moments of dark matter haloes
Using cosmological N -body simulations we study the radial velocity distribution in dark matter haloes focusing on the lowest-order even moments, dispersion and kurtosis. We determine the properties of ten massive haloes in the simulation box approximating their density distribution by the NFW formula characterized by the virial mass and concentration. We also calculate the velocity anisotropy ...
متن کاملDark Matter Halos as Bose-einstein Condensates
Galactic dark matter is modelled by a scalar field in order to effectively modify Kepler’s law without changing standard Newtonian gravity. In particular, a solvable toy model with a self-interaction U(Φ) borrowed from non-topological solitons produces already qualitatively correct rotation curves and scaling relations. Although relativistic effects in the halo are very small, we indicate corre...
متن کاملv 1 5 O ct 1 99 5 Solutions of the Einstein equations with matter
Recent results on solutions of the Einstein equations with matter are surveyed and a number of open questions are stated. The first group of results presented concern asymptotically flat spacetimes, both stationary and dy-namical. Then there is a discussion of solutions of the equations describing matter in special relativity and Newtonian gravitational theory and their relevance for general re...
