Black Hole Solutions in Rastall Theory
Y. Heydarzade, H. Moradpour, F. Darabi
The Reissner-Nordström black hole solution in a generic cosmological constant background in the the context of Rastall gravity is obtained. It is shown that the cosmological consta…
Bousso's Covariant Entropy Bound and Padmanabhan's Emergent Universe
H. Hadi, Y. Heydarzade, F. Darabi
We study the Padmanabhan's emergent Universe in the context of Bousso's covariant entropy conjecture. We find that for a flat Universe, this conjecture can be applied for the syste…
Evolution of spherical over-densities in tachyon scalar field model
M. R. Setare, F. Felegary, F. Darabi
We study the tachyon scalar field model in flat FRW cosmology with the particular potential and the scale factor behavior . We consider the spherical collapse mo…
On the stability of Einstein static universe at background level in massive bigravity
M. Mousavi, F. Darabi
We study the static cosmological solutions and their stability at background level in the framework of massive bigravity theory with Friedmann-Robertson-Walker (FRW) metrics. By th…
Emergent Cosmos in Einstein-Cartan Theory
H. Hadi, Y. Heydarzade, M. Hashemi +1
Based on the Padmanabhan's proposal, the accelerated expansion of the universe can be driven by the difference between the surface and bulk degrees of freedom in a region of space,…
