Primordial black holes within Higgs hybrid metric-Palatini approach
Brahim Asfour, Farida Bargach, Yahya Ladghami +2
In this paper, we investigate the production of primordial black holes (PBHs) during the radiation-dominated era. The collapse of significant density perturbations originating from…

Constraints on Power Law and Exponential models in Gravity
Dalale Mhamdi, Farida Bargach, Safae Dahmani +2
In this paper, we observationally test the \( f(Q) \) gravity model at both background and perturbation levels using Pantheon, Hubble measurements, and Redshift Space Distortio…

Diagnostic Approaches for Interacting generalized holographic Ricci Dark Energy Models
Omar Enkhili, Farida Bargach, Dalale Mhamdi +2
In this paper, we present an analytical solution for the interacting generalized holographic dark energy model, assuming a linear interaction rate between dark energy and dark matt…
