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…

Kalb-Ramond Black Holes Sourced by ModMax Electrodynamics: Some Perturbative Properties in the Phantom Sector

Y. Sekhmani, A. Baruah, S. K. Maurya +4

We formulate and analyze a new class of electrically charged black hole (BH) solutions in Lorentz-violating gravity, where nonlinear ModMax electrodynamics is nonminimally coupled…

Non-singular bouncing cosmology in gravity with energy condition violations

A. Zhadyranova, M. Koussour, V. Zhumabekova +3

The singularity and inflationary problems have posed significant challenges for understanding the universe's origin and evolution. Bouncing cosmology has emerged as a promising alt…

Constraints on CDM cosmology using Cosmic Chronometers and Supernova data

Yerlan Myrzakulov, M. Koussour, M. Bulanbay +2

In this manuscript, we investigate the constraints on dynamical vacuum models within the framework of CDM cosmology by assuming a parameterization of the vacuum energy densi…
