Observational Constraints on Emergent Fractional Fractal Cosmology
Raheleh Jalalzadeh, Hooman Moradpour, Shahram Jalalzadeh
We constrain the Emergent Fractional Fractal (EFF) cosmological model through a joint likelihood analysis of recent cosmological observations at the background and perturbation lev…
Finite Hilbert space and maximum mass of Schwarzschild black holes from a Generalized Uncertainty Principle
S. Jalalzadeh, H. Moradpour
We show that implementing a generalized uncertainty principle (GUP) with both minimal length and maximal momentum directly on the reduced phase space of the Schwarzschild black hol…
Constraining fractionality using some observational tests
H. Moradpour, S. Jalalzadeh, R. Jalalzadeh +1
Recently, a fractional version of the Schwarzschild-Tangherlini black hole with a fractal horizon has been introduced. Motivated by the key role of the Schwarzschild solution in gr…
Fractional Schwarzschild-Tangherlini black hole with a fractal event horizon
S. Jalalzadeh, H. Moradpour, G. R. Jafari +1
We demonstrate that the implementation of the fractional and non-local Wheeler--DeWitt (WDW) equation within the context of Schwarzschild geometry leads to the emergence of a Schwa…
Role of internal space correlations in the dynamics of a higher-dimensional Bianchi type-I universe: shear scalar and Hubble parameter perspectives
Nihan Katırcı
We investigate exact solutions of the Einstein field equations in higher-dimensional, spatially homogeneous Bianchi type-I spacetimes, introducing a real parameter that correla…
Unexplored regions in teleparallel gravity: Sign-changing dark energy density
Ozgur Akarsu, Bilal Bulduk, Antonio De Felice +2
While gravity has shown considerable potential in addressing cosmological tensions, we explore previously overlooked solution spaces that hold further promise. We examine th…
