Constraints on Rastall gravity from current observational data
Mahnaz Asghari, Hooman Moradpour
We study the cosmological features of Rastall gravity, where the covariant energy-momentum conservation is modified to in curved spacetime. For this purp…
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.…
Gravitational Collapse without Singularity Formation in Brans-Dicke Theory
A. H. Ziaie, H. Shabani, H. Moradpour
In the present work we study collapse process of a homogeneous and isotropic fluid in Brans-Dicke ({BD}) theory with non-vanishing spacetime torsion. In this theory, torsion can be…
Einstein Static Universe and its Stability in Generalized Rastall Gravity
Hamid Shabani, Amir Hadi Ziaie, Hooman Moradpour
The Einstein static (ES) state is a good candidate for describing the very early universe in terms of a regular cosmological model in which the Big Bang singularity is avoided. In…
A dynamical system representation of generalized Rastall gravity
Hamid Shabani, Hooman Moradpour, Amir Hadi Ziaie
In this work we study the phase-space analysis of generalized Rastall gravity (GRG) which has recently been introduced as a modification to the original version of Rastall gravity…
Gamow Temperature in Tsallis and Kaniadakis Statistics
Hooman Moradpour, Mohsen Javaherian, Ebrahim Namvar +1
Relying on the quantum tunnelling concept and Maxwell-Boltzmann-Gibbs statistics, Gamow shows that the star-burning process happens at temperatures comparable to a critical value,…
