Cluster Number Counts Dependence on Dark Energy Inhomogeneities and Coupling to Dark Matter
Cluster number counts can be used to test dark energy models. We investigate dark energy candidates which are coupled to dark matter. We analyze the cluster number counts dependence on the amount of dark matter coupled to dark energy. Further more, we study how dark energy inhomogeneities affect cluster abundances. It is shown that increasing the coupling reduces significantly the cluster numbe...
متن کاملClusters number counts dependence on dark energy inhomogeneities and coupling to dark matter
Many dark energy candidates have been proposed to explain the accelerated expansion the universe seems to be currently undertaking. Discriminating between them is likely to be a major issue in the near future, and cluster number counts would be a good tool for this. In this article we study scalar field candidates to dark energy which are coupled to dark matter. We focus on comparing the cluste...
متن کاملCoupling dark energy to dark matter inhomogeneities
We propose that dark energy in the form of a scalar field could effectively couple to dark matter inhomogeneities. Through this coupling energy could be transferred to/from the scalar field, which could possibly enter an accelerated regime. Though phenomenological, this scenario is interesting as it provides a natural trigger for the onset of the acceleration of the universe, since dark energy ...
متن کاملConstraining the coupling constant between dark energy and dark matter
We have investigated constraints on the coupling between dark matter and the interacting Chaplygin gas. Our results indicate that the coupling constant c between these two entities can take arbitrary values, which can be either positive or negative, thus giving arbitrary freedom to the inter-conversion between Chaplygin gas and dark matter. Thus, our results indicate that the restriction 0 < c ...
متن کاملAlternatives to Dark Matter and Dark Energy
We review the underpinnings of the standard Newton-Einstein theory of gravity, and identifywhere it could possibly go wrong. In particular, we discuss the logical independence from eachother of the general covariance principle, the equivalence principle and the Einstein equations, anddiscuss how to constrain the matter energy-momentum tensor which serves as the source of gravity.<lb...
