Charged particles and QPO constraints in tidal charge black hole magnetosphere sourced by a current loop
Ozodbek Abdurakhmonov, Javlon Rayimbaev, Inomjon Ibragimov +3
We investigate the dynamics of charged particles in the dipolar electromagnetic field generated by a stationary current loop around a static black hole in the Randall--Sundrum bran…
