In this work, we obtain uncharged∖ charged Kiselev-like black holes as a new class of black
hole solutions surrounded by perfect fluid in the context of Rastall theory. Then, we study the …

Here we consider a flat FRW universe whose horizon entropy meets the Rényi entropy of
nonextensive systems. In our model, the ordinary energy-momentum conservation law is not …

A generalized version for the Rastall theory is proposed showing the agreement with the
cosmic accelerating expansion. In this regard, a coupling between geometry and the …

Rotating black hole solutions in theories of modified gravity are important as they offer an
arena to test these theories through astrophysical observation. The non-rotating black hole …

The Reissner–Nordström black hole solution in a generic cosmological constant
background in the context of Rastall gravity is obtained. It is shown that the cosmological …

While the origin and composition of dark matter and dark energy remains unknown, it is
possible that they might represent two manifestations of a single entity, as occurring in …

In this paper, we study thermodynamics and thermodynamic geometry of a black hole
surrounded by the perfect fluid in Rastall theory. In particular, we calculate the physical …

In this paper, after referring to the Rastall theory, we address some of its cosmological
consequences. Moreover, bearing the Clausius relation in mind, using Friedman equations …

The restrictions on the Rastall theory due to application of the Newtonian limit to the theory
are derived. In addition, we use the zero‐zero component of the Rastall field equations as …

We present a new twisted rotating black hole solution by performing Demiański–Newman–
Janis algorithm to the electrically and dyonically charged black hole with quintessence in …
