A Six-Parameter Teleparallel Cosmology Beyond CDM: Sign-Changing Torsional Dark Energy and Implications for

Mohamed Bedair, Mahmoud Hashim, Jackson Levi Said +1

We investigate a particular case of the extended exponential infrared f(T) teleparallel gravity, in which the geometric sector naturally produces an effective dark-energy density t…

Cosmological Viability of Exponential Infrared Gravity

Mahmoud Hashim, Eleonora Di Valentino, Jackson Levi Said +1

We investigate the cosmological viability of exponential infrared teleparallel gravity using current cosmological observations. This framework realizes late-time cosmic acce…

Clustered unified dark sector cosmology: Background evolution and linear perturbations in light of observations

Mahmoud Hashim, Amr El-Zant

We consider unified dark sector models in which the fluid can collapse and cluster into halos, allowing for hierarchical structure formation to proceed as in standard cosmology. We…
