Thermodynamics and information recovery of Schwarzschild AdS black holes in conformal Killing gravity
Yahya Ladghami, Brahim Asfour, Francisco S. N. Lobo +1
We study Schwarzschild AdS black holes in conformal Killing gravity, focusing on their thermodynamics and information recovery via the island formula. Treating the cosmological con…
Testing Gauss-Bonnet Gravity with DESI BAO Data
Praveen Kumar Dhankar, Dalale Mhamdi, Albert Munyeshyaka +3
In the present paper, we observationally constrain f (G) gravity at the background level using Type Ia supernovae from the Pantheon Plus (PP) sample, cosmic chronometer (CC) data,…
Thermodynamic Topology of Black Holes within Tsallis Statistics
Yahya Ladghami, Brahim Asfour, Amine Bouali +2
In this paper, we investigate the thermodynamic topology of black holes within the framework of Tsallis statistics. By integrating Tsallis non-extensive statistics with topological…
From Barthel Randers Kropina Geometries to the Accelerating Universe: A Brief Review of Recent Advances in Finslerian Cosmology
Amine Bouali, Himanshu Chaudhary, Lehel Csillag +4
We review recent developments in cosmological models based on Finsler geometry and extensions of general relativity within this framework. Finsler geometry generalizes Riemannian g…
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…
Observational constraints on the growth index parameters in gravity
Dalale Mhamdi, Safae Dahmani, Amine Bouali +2
In this study, we analyse constraints on the growth index of matter perturbations, , within the framework of gravity, using recent cosmological observations, at the backg…
