Newtonian Shirokov Effect: Epicyclic Frequency Splitting from Mass Multipoles
Anuar Idrissov, Kuantay Boshkayev, Abylaikhan Tlemissov +1
We analyze small oscillations of nearly circular orbits in an axisymmetric Newtonian potential expanded in mass multipoles, as the classical counterpart of the relativistic Shiroko…
Polarized emission of orbiting hot-spots near Sagittarius A*: effects of electromagnetic interaction
Abylaikhan Tlemissov, Arman Tursunov, Maciek Wielgus
We investigate the polarimetric signatures of orbiting hot-spots around a Schwarzschild black hole in the presence of an external magnetic field, accounting for the electromagnetic…
Dynamical and observational properties of weakly Proca-charged black holes
Abylaikhan Tlemissov, Arman Tursunov, JiÅà KováŠ+1
The simplest approach to include a mass into the electromagnetic vector potential is to modify the Einstein-Maxwell action to the Einstein-Proca form. There are currently no exact…
Effect of nonlinear electrodynamics on polarization distribution around black hole
Abylaikhan Tlemissov, Bobir Toshmatov, JiÅà KováÅ
We have investigated the polarized images of synchrotron emission from magnetically charged, spherically symmetric regular Bronnikov black hole (in general relativity coupled to no…
