The Dark Side of the Universe
A. De Rújula
A view on the history and current status of dark matter and dark energy, at a fairly introductory level.
Perturbations of ultralight vector field dark matter
J. A. R. Cembranos, A. L. Maroto, S. J. Núñez Jareño
We study the dynamics of cosmological perturbations in models of dark matter based on ultralight coherent vector fields. Very much as for scalar field dark matter, we find two diff…
Isotropy theorem for arbitrary-spin cosmological fields
J. A. R. Cembranos, A. L. Maroto, S. J. Núñez Jareño
We show that the energy-momentum tensor of homogeneous fields of arbitrary spin in an expanding universe is always isotropic in average provided the fields remain bounded and evolv…
Solution to the Isotropy Problem for Cosmological Hidden Vector Models
J. A. R. Cembranos, A. L. Maroto, S. J. Nunez Jareno
Gauge bosons associated to new gauge symmetries under which the standard model particles are not charged are predicted in many extensions of the standard model of particles and int…
Isotropy theorem for cosmological Yang-Mills theories
J. A. R. Cembranos, A. L. Maroto, S. J. Núñez Jareño
We consider homogeneous non-abelian vector fields with general potential terms in an expanding universe. We find a mechanical analogy with a system of N interacting particles (with…
Branon dark matter: an introduction
J. A. R. Cembranos, A. Dobado, A. L. Maroto
This is a brief introduction to branon physics and its role in the dark matter problem. We pay special attention to the phenomenological consequences, both in high-energy particle…
