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…

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…
