In this paper we study the shadow of rotating Kaluza-Klein (KK) black holes and the connection between the shadow radius and the real part of quasinormal modes (QNMs) in the eiokonal limit. In addition we have explored the quasiperiodic oscillations (QPOs) in the rotating KK black hole.
Ghasemi-Nodehi et al. (Wed,) studied this question.
