Particle dynamics and Quasi-Periodic Oscillation around black holes surrounded by a Dehnen-type dark matter halo

In this article, we investigate the dynamics of test particles in the vicinity of black holes surrounded by a Dehnen-type dark matter halo. We find that increasing the dark matter parameters r_s and ρ_s enhances the tendency of particles to fall into the black hole. In addition, the orbital frequencies of particles moving around black holes embedded in Dehnen-type dark matter halos are analyzed.
