Dark energy parametrizations and their effect on dark halos
(Iop Publishing Ltd, 2006-07-01)
There are a plethora of dark energy parametrizations that can fit current supernovae Ia data. However, these data are only sensitive to redshifts up to order one. In fact, many of these parametrizations break down at higher ...

The imprint of the interaction between dark sectors in galaxy clusters
(IOP PUBLISHING LTD, 2010)
Based on perturbation theory, we study the dynamics of how dark matter and dark energy in the collapsing system approach dynamical equilibrium when they are in interaction. We find that the interaction between dark sectors ...
Observational constraints on holographic tachyonic dark energy in interaction with dark matter
(IOP PUBLISHING LTD, 2010)
We discuss an interacting tachyonic dark energy model in the context of the holographic principle. The potential of the holographic tachyon field in interaction with dark matter is constructed. The model results are compared ...
CCDM model with spatial curvature and the breaking of dark degeneracy
(Iop Publishing Ltd, 2016-01-01)
Creation of Cold Dark Matter (CCDM), in the context of Einstein Field Equations, leads to a negative creation pressure, which can be used to explain the accelerated expansion of the Universe. Recently, it has been shown ...
Clustering dark energy and halo abundances

Non-virialized clusters for detection of dark energy-dark matter interaction
(Oxford Univ Press, 2015-10-11)
The observation of galaxy and gas distributions, as well as cosmological simulations in a Lambda CDM cold dark matter universe, suggests that clusters of galaxies are still accreting mass and are not expected to be in ...
Some remarks on the attractor behaviour in ELKO cosmology
(Iop Publishing Ltd, 2014-08-01)
Recent results on the dynamical stability of a system involving the interaction of the ELKO spinor field with standard matter in the universe have been reanalysed, and the conclusion is that such system does not exhibit ...
