Timelike geodesics of a modified gravity black hole immersed in an axially symmetric magnetic field

Understand

We investigate the dynamics of a neutral and a charged particle around a black hole in modified gravity immersed in magnetic field.

• Our focus is on the scalar-tensor-vector theory as modified gravity.
• We are interested to explore the conditions on the energy of the particle under which it can escape to infinity after collision with another neutral particle in the vicinity of the black hole.
• We calculate escape velocity of particle orbiting in the innermost stable circular orbit (ISCO) after the collision.
