چکیده
We study the cosmological evolution for a scalar field dark matter model, by considering parameterization of equations that allow us to unify in single parameter family potentials: quadratic (free case), trigonometric (Axion-like and hyperbolic. After exploring dynamics this we perform statistical analysis viability such model comparison with standard Cold Dark Matter model. found free case is preferred over other potentials, but any all them are disfavored observations respect

Singlet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
متن کاملScalar Field Dark Matter and Galaxy Formation
We present a general description of the scalar field dark matter (SFDM) hypothesis in the cosmological context. The scenario of structure formation under such a hypothesis is based on Jeans instabilities of fluctuations of the scalar field. It is shown that it is possible to form stable long lived objects consisting of a wide range of typical galactic masses around 1012M⊙ once the parameters of...
متن کاملUnifying Dark Energy and Dark Matter with a Scalar Field
The standard model of cosmology considers the existence of two components of unknown nature, “dark matter” and “dark energy”, which determine the cosmological evolution. Their nature remains unknown, and other models can also be considered. In particular, it may be possible to reinterpret the recent cosmological observations so that the Universe does not contain two fluids of unknown natures, b...
متن کاملDark Matter and Dark Energy from a single scalar field
The strong CP problem was solved by Peccei & Quinn by introducing axions, which are a viable candidate for DM. Here the PQ approach is modified so to yield also Dark Energy (DE), which arises in fair proportions, without tuning any extra parameter. DM and DE arise from a single scalar field and, in the present ecpoch, are weakly coupled. Fluctuations have a fair evolution. The model is also fit...
