Axial Mode Stability and Quasinormal Modes of Charged Kiselev Black Holes in Rastall Gravity

Yan Wang, Yun-tao Gu, Wen-Di Guo

We investigate axial gravitoelectromagnetic perturbations of charged black holes surrounded by dust-like Kiselev-type anisotropic matter in Rastall gravity. We derive the axial mat…
