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…
