A Quadratic Equation of State to Cosmic Acceleration: Entropy Evolution and Phantom Crossing
A. Shahriar, M. Abbasiyan-Motlaq, M. Mohsenzadeh +1
This paper investigates the thermodynamic evolution of the universe within the framework of a quadratic equation of state (EoS). Building upon the basis of the quadratic EoS model,…
A possible role for the merger of clusters/voids in the cosmological expansion
S. Mohammadi, E. Yusofi, M. Mohsenzadeh +1
In this study, we use the merger process of clusters/voids in the role of variable dark energy fluid to alleviate the Hubble tension, which can lead to a balance in the cosmologica…
Cosmological Constant Problem and Tension in Void-dominated Cosmology
E. Yusofi, M. A. Ramzanpour
In this work, we study the cosmological constant problem and Hubble tension in the void-dominated cosmology scenario \cite{Yusofi:2022hgg}. For this goal, we will first consider th…
Surface Tension of Cosmic Voids as a Possible Source for Dark Energy
E. Yusofi, M. Khanpour, B. Khanpour +2
The cosmological constant is estimated by considering the surface tension of supervoids in a void-dominated cosmic fluid by which we can get a possible source of dark energy. Looki…
Gravitational Merging as a Possible Source for the Cosmological Accelerating
Mehrdad Khanpour, Ebrahim Yusofi, Bahman Khanpour
Gravitational merging (or clustering) of cosmic objects is regarded as a possible source of the extra-acceleration of the universe at large scale. The merging/clustering of cosmic…
Reconstruction of initial Asymptotic-de Sitter mode in light of the Planck data
Hossein Moshafi, Ata Sojasi, Ebrahim Yusofi +1
The recently relased \emph{Planck} data, emphasize that the background geometry of inflation is not pure de Sitter, but from the slow variation of Hubble parameter during the infla…
