Unified Dark Matter Scalar Field Models [PDF]
Advances in Astronomy, 2010 We analyze and review cosmological models in which the dynamics of a single scalar field accounts for a unified description of the Dark Matter and Dark Energy sectors, dubbed Unified Dark Matter (UDM) models.

The continuous tower of scalar fields as a system of interacting dark matter–dark energy [PDF]
Physics Letters B, 2015 This paper aims to introduce a new parameterisation for the coupling Q in interacting dark matter and dark energy models by connecting said models with the Continuous Tower of Scalar Fields model.

Brief History of Ultra-light Scalar Dark Matter Models [PDF]
EPJ Web of Conferences, 2018 This is a review on the brief history of the scalar field dark matter model also known as fuzzy dark matter, BEC dark matter, wave dark matter, or ultra-light axion. In this model ultra-light scalar dark matter particles with mass m = O(10-22)eV condense

Scalar field dark matter and the Higgs field [PDF]
Physics Letters B, 2016 We discuss the possibility that dark matter corresponds to an oscillating scalar field coupled to the Higgs boson. We argue that the initial field amplitude should generically be of the order of the Hubble parameter during inflation, as a result of its ...

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.

Effective field theory and scalar triplet dark matter
Journal of High Energy PhysicsWe discuss an extension of the standard model with a real scalar triplet, T, including non-renormalizable operators (NROs) up to d = 6. If T is odd under a Z 2 symmetry, the neutral component of T is a good candidate for the dark matter (DM) of the ...

Can Dark Matter be a Scalar Field? [PDF]
Journal of Cosmology and Astroparticle Physics, 2016 In this paper we study a real scalar field as a possible candidate to explain the dark matter in the universe. In the context of a free scalar field with quadratic potential, we have used Union 2.1 SN Ia observational data jointly with a Planck prior ...

Galactic collapse of scalar field dark matter [PDF]
Classical and Quantum Gravity, 2002 We present a scenario for galaxy formation based on the hypothesis of scalar field dark matter. We interpret galaxy formation through the collapse of a scalar field fluctuation. We find that a cosh potential for the self-interaction of the scalar field provides a reasonable scenario for galactic formation, which is in agreement with cosmological ...
