文摘We study the quasinormal modes （QNMs） of a Schwarzschild black hole immersed in an electromagnetic （EM） universe. The immersed Schwarzschild black hole （ISBH） originates from the metric of colliding EM waves with double polarization [Class. Quantum Grav. 12, 3013 （1995）]. The perturbation equations of the scalar fields for the ISBH geometry are written in the form of separable equations. We show that these equations can be transformed to the confluent Heun＇s equations, for which we are able to use known techniques to perform analytical quasinormal （QNM） analysis of the solutions. Furthermore, we employ numerical methods （Mashhoon and 6^th-order Wentzel- Kramers-Brillouin （WKB）） to derive the QNMs. The results obtained are discussed and depicted with the appropriate plots.
