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…
