Scalar field dark matter in clusters of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 One alternative to the cold dark matter (CDM) paradigm is the scalar field dark matter (SFDM) model, which assumes dark matter is a spin-0 ultra-light scalar field (SF) with a typical mass $m\sim10^{-22}\mathrm{eV}/c^2$ and positive self-interactions ...

Scalar Field (Wave) Dark Matter [PDF]
The Fourteenth Marcel Grossmann Meeting, 2016 Recent high-quality observations of dwarf and low surface brightness (LSB) galaxies have shown that their dark matter (DM) halos prefer flat central density profiles.

Is Sextans dwarf galaxy in a scalar field dark matter halo? [PDF]
, 2014 The Bose-Einstein condensate/scalar field dark matter model, considers that the dark matter is composed by spinless-ultra-light particles which can be described by a scalar field.

Cosmological constraints on scalar field dark matter [PDF]
International Journal of Modern Physics D, 2015 This paper aims to put constraints on the parameters of the Scalar Field Dark Matter (SFDM) model, when dark matter is described by a free real scalar field filling the whole universe, plus a cosmological constant term.

Scalar field dark matter with a cosh potential, revisited [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 Dark matter models in which the constituent particle is an ultra-light boson have become part of the mainstream discussion in cosmology and astrophysics.

Scalar-field dark energy nonminimally and kinetically coupled to dark matter [PDF]
Physical Review D, 2019 We provide a general framework for studying the dark energy cosmology in which a scalar field ϕ is nonminimally and kinetically coupled to cold dark matter (CDM).

Supplying dark energy from scalar field dark matter [PDF]
International Journal of Modern Physics D, 2017 We consider the hypothesis that dark matter (DM) and dark energy (DE) consist of ultra-light self-interacting scalar particles. It is found that the Klein–Gordon equation with only two free parameters (mass and self-coupling) on a Schwarzschild ...

Small scale structures in coupled scalar field dark matter
Physics 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.
