Orbital stability, relativistic precession, and QPO constraints for constant-curvature black holes in gravity
Kourosh Nozari, Sara Saghafi, Khadijeh Salahshour +1
We analyze circular-orbit stability, epicyclic resonances, relativistic precession, and quasi-periodic-oscillation (QPO) constraints in the constant-curvature vacuum sector of metr…
Phenomenological Rotating Extension of 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 circularity…
Dimensional Phenomenology in Polymeric Quantization Framework
Kourosh Nozari, Hamed Ramezani
In this paper, we study the statistical mechanics within the polymer quantization framework in the semiclassical regime. We apply a non-canonical transformation to the phase space…
Accretion Process as a Probe of Extra Dimensions in MOG Compact Object Spacetimes
Kourosh Nozari, Sara Saghafi, Zeynab Ramezanpasandi
The idea of extra spatial dimensions arises from attempts to unify gravity with other fundamental interactions, develop a consistent theory of quantum gravity, and address open pro…
Shadow of Extreme Compact Charged Objects in Consistent 4-Dimensional Einstein-Gauss-Bonnet Gravity
Sara Saghafi, Kourosh Nozari, Maryam Kaveh
In order to better describe gravitational phenomena on both very small and cosmological scales, there have been constant attempts to generalize and expand the theory of General Rel…
Linear-Quadratic GUP and Thermodynamic Dimensional Reduction
H. Ramezani, K. Nozari
In this paper we investigate the statistical mechanics within the Linear-Quadratic GUP (LQGUP, i.e, GUP with linear and quadratic terms in momentum) models in the semiclassical reg…
