In this paper, we investigate the dark energy phenomenon by studying the Tsallis
holographic dark energy within the framework of Brans–Dicke (BD) scalar–tensor theory of …

In this work, we mainly focus on testing the spacetime properties around black holes
surrounded by a dark fluid, which are potential candidates for dark energy described by the …

In this review paper, several new results towards the explanation of the accelerated
expansion of the large-scale universe is discussed. On the other hand, inflation is the early …

In this work devoted to the investigation of the Tsallis holographic dark energy (IR cut-off is
Hubble radius) in homogeneous and anisotropic Kantowski–Sachs Universe within the …

We revise the cosmological interaction between dark energy and dark matter. More
precisely, we focus on models that support compartmentalization or coexistence in the dark …

In this paper we discuss a phase space analysis of various interacting Chaplygin gas
models in general relativity. Linear and nonlinear sign changeable interactions are …

In this paper, we attempt to explore the possibility of a obtaining a viable emergent universe
scenario supported by a type of fluid known as the extended Chaplygin gas, which extends …

We analyze the global nonlinear stability of FLRW (Friedmann-Lemaître-Robertson-Walker)
spacetimes in the presence of an irrotational perfect fluid. We assume that the fluid is …

This paper deals with the dynamical systems analysis of Friedmann–Robertson–Walker
(FRW) model of the Universe in the framework of general relativity with quadratic equation of …

We explore exact f (R) gravity solutions that mimic Chaplygin-gas inspired Λ CDM
cosmology. Starting with the original, generalized and modified Chaplygin-gas (MCG) …
