Observational Constraints on the Dark Energy with a Quadratic Equation of State
Hossein Moshafi, Alireza Talebian, Ebrahim Yusofi +1
In this study, we introduce a novel late-time effective dark energy model characterized by a quadratic equation of state (EoS) and rigorously examine its observational constraints.…
Multiple transitions in vacuum dark energy and tension
Hossein Moshafi, Hassan Firouzjahi, Alireza Talebian
We study the effects of multiple transitions in the vacuum dark energy density on the tension problem. We consider a phenomenological model in which the vacuum energy density…
Observational constraints on the interacting dark energy - dark matter (IDM) cosmological models
T. Harko, K. Asadi, H. Moshafi +1
Particle creation (or annihilation) mechanisms, described by either quantum field theoretical models, or by the thermodynamics of irreversible processes, play an important role in…
Minimal warm inflation and TCC
Vahid Kamali, Hossein Moshafi, Saeid Ebrahimi
The minimal warm inflation model was constructed as a warm inflation setup with direct interaction between inflaton and (non-Abelian) gauge fields. The model was shown to be compat…
CMB lensing in a modified CDM model in light of the tension
Hossein Moshafi, Shant Baghram, Nima Khosravi
The observed discrepancy of the Hubble parameter measurements in the local universe with the cosmic microwave background (CMB) data may indicate a new physics. It is vital to test…
The Integrated Sachs-Wolfe Effect in the Bulk Viscous Dark Energy Model
B. Mostaghel, H. Moshafi, S. M. S. Movahed
We examine linear perturbation theory to evaluate the contribution of viscosity coefficient in the growing of dark matter perturbations in the context of the bulk viscous dark ener…
