Non-minimal Unimodular Inflation
Manda Malekpour, Kourosh Nozar, Fateme Rajabi +1
We study an extension of the unimodular cosmological inflation in the context of the non-minimal coupling of a generic scalar field with gravitational sector. We consider the non-m…
Higher Dimensional Loop Quantum Black hole in de Sitter Spacetime: Quasinormal Modes and Shadow Signatures
Sara Saghafi, Kourosh Nozari, Ali Mohammadpour
We investigate the dynamical and optical properties of a higher-dimensional loop-quantum-corrected black hole in a de Sitter background. We first analyze the horizon structure and…
Thin Accretion Disks around Rotating Charged Black Holes in an Effective Higher-Curvature Spacetime
Mohammad Hassani, Kourosh Nozari, Sara Saghafi
We investigate the structure and emission properties of a thin accretion disk around a rotating charged black hole described by an effective higher-curvature-inspired spacetime, co…
Beyond : Gauss--Bonnet inflation with
Ali Seidabadi, Sara Saghafi, Kourosh Nozari
Gauss--Bonnet inflation typically affects the dynamics over an extended portion of the trajectory, making it difficult to isolate a controlled imprint at CMB scales. We consider a…
Investigating QED Effects on the Thin Accretion Disk Properties Around Rotating Euler-Heisenberg Black Holes
Kourosh Nozari, Sara Saghafi, Fatemeh Aliyan
The Einstein Euler Heisenberg (EEH) black hole model represents an extension of classical black hole solutions in general relativity by incorporating quantum electrodynamic (QED) c…
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…
