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…
Reheating after the Higgs Inflation
Manda Malekpour, Kourosh Nozari
Since the discovery of the Higgs particle in the LHC, numerous inflationary models utilize it as the inflaton. In this study, after establishing that Higgs inflation can be a viabl…
Effective reheating in Gauss--Bonnet inflation with coupling
Ali Seidabadi, Sara Saghafi, Kourosh Nozari
We study effective reheating in a scalar--Gauss--Bonnet inflationary model with a phase-space-dependent coupling , in which a compact field-space feature is combined with a…
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…
