Einstein Static Universe in Rastall Theory of Gravity
F. Darabi, K. Atazadeh, Y. Heydarzade
We investigate stability of the Einstein static solution against homogeneous scalar, vector and tensor perturbations in the context of Rastall theory of gravity. We show that this…
Surrounded Vaidya Solution by Cosmological Fields
Y. Heydarzade, F. Darabi
In the present work, we study the general surrounded Vaidya solution by the various cosmological fields and its nature describing the possibility of the formation of naked singular…
Vaidya Spacetime in Massive Gravity's Rainbow
Yaghoub Heydarzade, Prabir Rudra, Farhad Darabi +2
In this paper, we will analyze the energy dependent deformation of massive gravity using the formalism of massive gravity's rainbow. So, we will use the Vainshtein mechanism and th…
Braneworld Black Holes and Entropy Bounds
Y. Heydarzade, H. Hadi, C. Corda +1
The Bousso's D-bound entropy for the various possible black hole solutions on a 4-dimensional brane is checked. It is found that the D-bound entropy here is apparently different fr…
A Generalization to the Rastall Theory and Cosmic Eras
H. Moradpour, Y. Heydarzade, F. Darabi +1
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 pressurel…
Black Hole Solutions Surrounded by Perfect Fluid in Rastall Theory
Y. Heydarzade, F. Darabi
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 stu…
