Charged fluid tori with an approximate magnetic self-field around magnetized Schwarzschild black holes: A semi-analytic approach
Abylaikhan Tlemissov, Jiri Kovar
We study toroidal structures formed by a charged, non-self-gravitating perfect fluid orbiting a Schwarzschild black hole immersed in a poloidal magnetic field. To obtain analytic a…
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, Jiří Kovář +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…
