Probing the Three-Dimensional Structure of a Jet with Faraday Tomography
Sawera Gull, Masaya Kurogi, Keitaro Takahashi
Magnetic fields play a fundamental role in the dynamics and radiation of jets associated with active galactic nuclei (AGNs), where they accelerate and collimate the relativistic pl…
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…
Anisotropic Generalized Polytropic Spheres: Regular 3D Black Holes
Seyed Naseh Sajadi, Mohsen Khodadi, Orlando Luongo +1
We model gravitating relativistic 3D spheres composed of an anisotropic fluid in which the radial and transverse components of the pressure correspond to the vacuum energy and a ge…
Instability and no-hair paradigm in d-dimensional charged-AdS black holes
Afsaneh Rahmani, Mohsen Khodadi, Matin Honardoost +1
Is it possible the no-hair paradigm is violated when a black hole undergoes an instability? Employing massless charged scalar perturbations, we address this question within the con…
Black holes with scalar hair in light of the Event Horizon Telescope
Mohsen Khodadi, Alireza Allahyari, Sunny Vagnozzi +1
Searching for violations of the no-hair theorem (NHT) is a powerful way to test gravity, and more generally fundamental physics, particularly with regards to the existence of addit…
Magnetically charged black holes from non-linear electrodynamics and the Event Horizon Telescope
Alireza Allahyari, Mohsen Khodadi, Sunny Vagnozzi +1
Non-linear electrodynamics (NLED) theories are well-motivated extensions of QED in the strong field regime, and have long been studied in the search for regular black hole (BH) sol…
Mimetic Black Holes
Mohammad Ali Gorji, Alireza Allahyari, Mohsen Khodadi +1
In this paper, we look for the vacuum static spherically symmetric solution in the mimetic gravity scenario based on the conformal invariance principle. The trivial solution is a s…
Emergent universe in Horava-Lifshitz-like F(R) gravity
M. Khodadi, Y. Heydarzade, F. Darabi +1
We investigate the Einstein static universe (ESU) and the emergent universe scenario in the framework of Hořava-Lifshitz-like gravity. We first perform a dynamical analysis…
