Crossing the phantom divide line in universal extra dimensions
Nasr Ahmed, Anirudh Pradhan
We investigate the cosmic acceleration and the evolution of dark energy across the cosmological constant boundary in universal extra dimensions UED. We adopt an empirical approach…
The possibility of a stable flat dark energy-dominated Swiss-cheese Brane-world universe with a deceleration-acceleration transition
Nasr Ahmed, Kazuharu Bamba, F. Salama
In this paper, we study the possibility of obtaining a stable flat dark energy-dominated universe in a good agreement with observations in the framework of Swiss-cheese Brane-world…
A Cyclic Universe With Varying Cosmological Constant in gravity
Nasr Ahmed, Sultan Z. Alamri
A new kind of evolution for cyclic models in which the Hubble parameter oscillates and keeps positive has been explored in a specific gravity reconstruction. A singularity…
Cosmological determination to the values of the prefactors in the logarithmic corrected entropy-area relation
Nasr Ahmed, Sultan Z. Alamri
In this paper, we continue investigating the possible values of the pre-factors and in the logarithmic corrected entropy-area relation based on cosmological stability argum…
Ricci-Gauss-Bonnet holographic dark energy in Chern-Simons modified gravity: A flat FLRW quintessence-dominated universe
Nasr Ahmed
We discuss the recently suggested Ricci-Gauss-Bonnet holographic dark energy in Chern-Simons modified gravity. We have tested some general forms of the scale factor , and use…
