Quasinormal modes and the correspondence with shadow in a charged black hole in presence of quintessence
Chuanhong Gao, Deyou Chen, Chengye Yu
In this paper, we investigate the photon sphere, shadow radius and quasinormal modes of a charged black hole in presence of quintessence. The result shows that the shadow radius de…

The correspondence between shadow and test field in a four-dimensional charged Einstein-Gauss-Bonnet black hole
Deyou Chen, Chuanhong Gao, Xianming Liu +1
In this paper, we investigate the photon sphere, shadow radius and quasinormal modes of a four-dimensional charged Einstein-Gauss-Bonnet black hole. The perturbation of a massless…
