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…
Topological Signatures and Geometrothermodynamics of Critical Phenomena in Regularized Maxwell Black Holes
Y. Sekhmani, G. G. Luciano, S. K. Maurya +4
We study the thermodynamic topology and microscopic interaction properties of charged black holes in RegMax gravity, focusing on the role of the coupling parameter . Using the…
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…
