Observational constraints on New Tsallis holographic energy in Rastall theory
N. Sadeghnezhad, R. Jalalzadeh, Z. Davari +1
The cosmological implications of New Tsallis holographic dark energy (NTHDE) in Rastall theory have been studied. Using the data set that includes DESI BAO (DR2), PantheonPlus SNe…
Cosmological Singularities in Brane Gravity
R. Jalalzadeh, S. Jalalzadeh, Y. Heydarzade
We present a comprehensive study of cosmological singularities within the framework of Covariant Extrinsic Gravity (CEG), addressing both the initial Big Bang singularity and poten…
Observational constraints on FLRW, Bianchi type I and V brane models
R. Jalalzadeh, S. Jalalzadeh, B. Malekolkalami +1
This study explores the compatibility of Covariant Extrinsic Gravity (CEG) with current cosmological observations. We employ the chi-square statistic and Markov Chain Monte Carlo (…
Friedmann equations of the fractal apparent horizon
R. Jalalzadeh, S. Jalalzadeh, A. Sayahian Jahromi +1
From a fractal perspective, the entropy bound of gravitational systems undergoes changes. Furthermore, in the cosmological setting, the conservation law of a perfect fluid is also…
Probing extra dimensions through cosmological observations of dark energy
R. Jalalzadeh, S. Jalalzadeh, B. Malekolkalami
We investigate the isometrically embedded Bianchi type-V cosmology braneworld model in a -dimensional bulk space. The model provides a fluid of geometric dark energy (GDE) and u…
