Dynamical dark energy in the Bianchi Type-V Universe with DESI DR2 BAO, SNIa compilation and RSD measurements
Shambel Sahlu, Ãlvaro de la Cruz-Dombriz, A. H. A. Alfedeel +2
We investigate the cosmological implications of dynamical dark energy (DDE) models within an anisotropic, spatially homogeneous Bianchi Type-V spacetime framework using a cov…
Analytic semiclassical backreaction of a Schwarzschild black hole in a finite cavity: horizon shift, temperature renormalization, and canonical stability in the Hartle-Hawking State
G. G. L. Nashed, Alnadhief H. A. Alfedeel, Tiberiu Harko
We construct an analytic model of static semiclassical backreaction for a Schwarzschild black hole in the Hartle--Hawking state enclosed within a finite spherical cavity. Using a m…
Observational constraints on viscous cosmology in gravity
M. Koussour, Alnadhief H. A. Alfedeel, S. Muminov +1
We investigate the late-time cosmic acceleration within the framework of viscous gravity, where the gravitational action depends on both the torsion scalar and the m…
Modified cosmology in gravity
Y. Myrzakulov, Alnadhief H. A. Alfedeel, M. Koussour +3
In this letter, we investigate cosmology within the framework of modified gravity using the non-linear model , where , , and …
Quintessence phase of the late-time Universe in gravity
Shambel Sahlu, Bhupendra Kumar Shukla, Rishi Kumar Tiwari +2
In this paper, we have studied the late-time accelerating expansion of the Universe using the matter-geometry coupled gravity model, where is the non-metricity sc…
