RSD constraints on power-law gravity using Barboza-Alcaniz and Jassal-Bagla-Padmanabhan parametrizations
Chaymae karam, Dalale Mhamdi, Taoufik Ouali +2
We investigate the late-time accelerated expansion of the Universe in power-law gravity, , combined with two dynamical dark…
Black Holes Thermodynamic Topology in Sharma-Mittal Statistics
Issam Najma, Yahya Ladghami, Amine Bouali +1
In this study, we explore the thermodynamic topology of black holes within the Sharma-Mittal entropy framework. Our study covers several black hole solutions, including charged and…
Testing Gravity with Logarithmic Equation of State Using Latest Cosmological Data
Chaymae Karam, Dalale Mhamdi, Taoufik Ouali +2
In this paper, we investigate the late-time accelerated expansion of the Universe in power law gravity, where a logarithmic dark energy parametrization is considered: $ω_{de…
Testing the bulk viscosity within the f(R,T) gravity in light of DESI-DR2 observations
Omayma Saddiki, Safae Dahmani, Taoufik Ouali +1
We investigate the cosmological implications of the bulk viscosity within the framework of gravity by considering the linear model , where characterizes…
Testing the running vacuum model in light of DESI-DR2 Measurements
Lamiae Kardaddech, Safae Dahmani, Amine Bouali +2
Motivated by the fact that quantum effects leave an imprint on the vacuum equation of state, making it depart from the standard cosmological constant relation, $P_{\rm vac}=-ρ_{\rm…
Dark Matter Signatures in Black Hole Thermodynamics and Information Recovery
Yahya Ladghami, Brahim Asfour, Taoufik Ouali
In this paper, we investigate the thermodynamic properties and information recovery of Schwarzschild and Reissner--Nordstr"om black holes surrounded by perfect fluid dark matter. W…
Cosmological test of a length-preserving biconnection gravity
Dalale Mhamdi, Amine Bouali, Taoufik Ouali +1
We investigate the cosmological implications of an extended gravitational framework based on biconnection gravity, constructed from the Schrdinger connection and its dual…
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…
Gravitational waves production during preheating within GB gravity with monomial coupling
Brahim Asfour, Yahya Ladghami, Taoufik Ouali
In this paper, we investigate the production of gravitational waves during the preheating era. To achieve this purpose, we consider Gauss-Bonnet inflation model with Power{\textend…
Reconstruction of the Quintessence Scalar Field Potential Using Gaussian Processes
Redouane El Ouardi, Amine Bouali, Ahmed Errahmani +3
Recent cosmological observations, including the latest Dark Energy Spectroscopic Instrument (DESI) data releases DR1 and DR2, have renewed interest in the possibility that dark ene…
Study of the cosmological tensions and DESI-DR2 in the framework of the Little Rip model
Safae Dahmani, Imad El Bojaddaini, Amine Bouali +2
We present an analysis that investigates the and tensions by considering a dark energy model. The latter is a late-time model characterized by a future abrupt event kno…
Timelike Entanglement Entropy of Hawking Radiation
Yahya Ladghami, Francisco S. N. Lobo, Taoufik Ouali
We introduce the concept of timelike entanglement entropy of Hawking radiation as a novel probe of the black hole information paradox. By analytically continuing black hole spaceti…
