A winding number analysis of Schwarzschild black hole stability in light of Planck-scale modified kinematics
Mohsen Khodadi, Nosratolla Jafari, Shahin Mamedov
Determining whether Planck-scale effects can stabilize black holes addresses fundamental questions about black hole evaporation and quantum gravity consistency. Here, we analyze th…
Multi-probe analysis of strong-field effects in gravity
Mohsen Khodadi, Behnam Pourhassan, Emmanuel N. Saridakis
Covariant gravity is a viable extension of General Relativity, however its strong-field predictions remain largely untested. Using the static, spherically symmetric black-ho…
Atomic clocks and gravitational waves as probes of non-metricity
Mohsen Khodadi, Emmanuel N. Saridakis
Non-metricity provides a natural extension of Riemannian geometry, yet its experimental signatures remain largely unexplored. In this work, we investigate how spacetime non-metrici…
The Weyl Geometric Gravity black hole in light of the Solar System tests
Mohsen Khodadi, Tiberiu Harko
The Weyl geometric gravity theory, in which the gravitational action is constructed from the square of the Weyl curvature scalar and the strength of the Weyl vector, has been inten…
