Phase-Space Analysis of Quadratic Dark Energy: Stable Attractors and Their Observational Signatures
Sahar Mohammadi, Ebrahim Yusofi, Kosar Asadi
We present a comprehensive phase-space analysis of a quadratic dark energy model where the pressure includes a nonlinear term proportional to the square of the energy density. This…
A Dark Matter Model with Quadratic Equation of State: Background Evolution and Structure Formation
Kazem Rezazadeh, Ebrahim Yusofi, Alireza Talebian
We propose that dark matter (DM) possesses a quadratic equation of state, which becomes significant at high densities, altering the Universe's evolution during its early stages. We…
Stability and Thermodynamics of a Generalized Power-Law Dark Energy Model
S. Kazemi, M. A. Ramzanpour, E. Yusofi +1
We investigate a generalized power-law dark energy equation of state of the form in a flat FLRW universe, analyzing its dynamical stability and thermodynamic consist…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Modified Uncertainty Principle with Cosmological Constant: More Insights on Dark Energy and Chandrasekhar Limit
S. Ahmadi, E. Yusofi, M. A. Ramzanpour
Numerous studies have shown that generalized uncertainty principle (GUP) removes the Chandrasekhar limit, which can be restored using a negative GUP parameter. This study indicates…
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.…
Incorporating the Cosmological Constant in a Modified Uncertainty Principle
S. Ahmadi, E. Yusofi, M. A. Ramzanpour
This study explores the cosmological constant problem and modified uncertainty principle within a unified framework inspired by a void-dominated scenario. In a recent paper~\cite{Y…
