Constraining condensate dark matter in galaxy clusters
J. C. C. de Souza, M. Ujevic
We constrain scattering length parameters in a Bose-Einstein condensate dark matter model by using galaxy clusters radii, with the implementation of a method previously applied to…
Discussion on the energy content of the galactic dark matter Bose-Einstein condensate halo in the Thomas-Fermi approximation
J. C. C. de Souza, M. O. C. Pires
We show that the galactic dark matter halo, considered composed of an axionlike particles Bose-Einstein condensate \cite{pir12} trapped by a self-graviting potential \cite{boh07},…
Domain Wall Model in the Galactic Bose-Einstein Condensate Halo
J. C. C. de Souza, M. O. C. Pires
We assume that the galactical dark matter halo, considered composed of an axionlike particles Bose-Einstein condensate \cite{pir12}, can present topological defects, namely domain…
Exact cosmological solutions of models with an interacting dark sector
A. B. Pavan, Elisa G. M. Ferreira, Sandro M. R. Micheletti +2
In this work we extend the first order formalism for cosmological models that present an interaction between a fermionic and a scalar field. Cosmological exact solutions describing…
Signature of the interaction between dark energy and dark matter in observations
Elcio Abdalla, L. Raul Abramo, Jose C. C. de Souza
We investigate the effect of an interaction between dark energy and dark matter upon the dynamics of galaxy clusters. This effect is computed through the Layser-Irvine equation, wh…
