The growth of DM and DE perturbations in DBI non-canonical scalar field scenario
K. Rezazadeh, S. Asadzadeh, K. Fahimi +2
We study the effect of varying sound speed on clustering dark energy in the Dirac-Born-Infeld (DBI) scenario. The DBI action is included in the class of -essence models, and it…
Structure formation in clustering DBI dark energy model with constant sound speed
K. Fahimi, K. Karami, S. Asadzadeh +1
Within the framework of DBI non-canonical scalar field model of dark energy, we study the growth of dark matter perturbations in the both linear and non-linear regimes. In our DBI…
Structure formation and generalized second law of thermodynamics in some viable -gravity models
S. Asadzadeh, M. S. Khaledian, K. Karami
Here, we investigate the growth of matter density perturbations as well as the generalized second law (GSL) of thermodynamics in the framework of -gravity. We consider a spat…
Cosmological constraints on polytropic gas model
K. Karami, Z. Safari, S. Asadzadeh
We study the polytropic gas scenario as the unification of dark matter and dark energy. We fit the model parameters by using the latest observational data including type Ia superno…
QCD modified ghost scalar field dark energy models
K. Karami, S. Asadzadeh, M. Mousivand +1
Within the framework of FRW cosmology, we study the QCD modified ghost scalar field models of dark energy in the presence of both interaction and viscosity. For a spatially non-fla…
QCD ghost f(T)-gravity model
K. Karami, A. Abdolmaleki, S. Asadzadeh +1
Within the framework of modified teleparallel gravity, we reconstruct a f(T) model corresponding to the QCD ghost dark energy scenario. For a spatially flat FRW universe containing…
