Confronting the Chaplygin gas with data: background and perturbed cosmic dynamics
Shambel Sahlu, Heba Sami, Renier Hough +3
In this paper, we undertake a unified study of background dynamics and cosmological perturbations in the presence of the Chaplygin gas. This is done by first constraining the backg…
Thermodynamic geometry of static and rotating regular black holes in conformal massive gravity
Saheb Soroushfar, Reza Saffari, Amare Abebe +1
A version of massive gravity, namely conformal massive gravity, is employed to study the behavior of thermodynamic geometry for both the static and the rotating regular black holes…
Cosmic hierarchy in gravity
Heba Sami, Amare Abebe
In this contribution, we investigate hierarchical nature of large-scale structure clustering through the oscillatory nature of the solutions of the Schrödinger-like Friedmann equat…
Covariant density and velocity perturbations of the quasi-Newtonian cosmological model in gravity
Heba Sami, Shambel Sahlu, Amare Abebe +1
We investigate classes of shear-free cosmological dust models with irrotational fluid flows within the framework of gravity. In particular, we use the covariant form…
