Rotating Black Holes with Primary Scalar Hair: Shadow Signatures in Beyond Horndeski Gravity
Kourosh Nozari, Milad Hajebrahimi, Sara Saghafi +2
The Event Horizon Telescope (EHT) image of M87* provides a direct test of strong-field gravity, measuring an angular shadow diameter and a circularit…

Circular orbits and accretion disk around a deformed-Schwarzschild black hole in loop quantum gravity
Kourosh Nozari, Sara Saghafi, Milad Hajebrahimi +1
In this paper, we study the motion of neutral and electrically charged particles in the vicinity of a deformed-Schwarzschild black hole inspired by Loop Quantum Gravity (LQG). To e…

Extended Uncertainty Principle: A Deeper Insight into the Hubble Tension?
Kourosh Nozari, Sara Saghafi, Milad Hajebrahimi
The standard cosmological model, known as the LambdaCDM model, has been successful in many respects, but it has some significant discrepancies, some of which have not been resolved…
