Non-Singular Bouncing cosmology from Phantom Scalar-Gauss-Bonnet Coupling: Reconstruction with Observational Insights
Khandro K. Chokyi, Surajit Chattopadhyay
We examine non-singular bounce cosmology within the framework of a phantom scalar field coupled to the Gauss-Bonnet term in both non-viscous and bulk-viscous cases. Using the scale…

A Combined Barrow Entropy and QCD Ghost Mechanism for Late-Time Cosmic Acceleration
Aziza Altaibayeva, Ulbossyn Ualikhanova, Zhanar Umurzakhova +1
We investigate a unified dark-energy scenario based on the combined effects of Barrow entropy corrections and the QCD ghost mechanism, referred to as the BH--QCDGDE model. The dark…
