Ringing and echoes from black bounces surrounded by the string cloud
Yi Yang, Dong Liu, Zhaoyi Xu +1
In the string theory, the fundamental blocks of nature are not particles but one-dimensional strings. Therefore, a generalization of this idea is to think of it as a cloud of strin…
Quasinormal modes of Kerr-like black bounce spacetime
Yi Yang, Dong Liu, Ali Övgün +2
We investigate the quasinormal mode (QNM) spectrum of a Kerr-like black-bounce spacetime under massive scalar-field perturbations. Starting from the Kerr-like deformation of the Si…
Gravitational ringing and superradiant instabilities of the Kerr-like black holes in a dark matter halo
Dong Liu, Yi Yang, Ali Övgün +2
Supermassive black holes from the center of galaxy may be immersed in a dark matter halo. This dark matter halo may form a "cusp" structure around the black hole and disappear at a…
The ringing of quantum corrected Schwarzschild black hole with GUP
Yujia Xing, Yi Yang, Dong Liu +2
Schwarzschild black holes with quantum corrections are studied under scalar field perturbations and electromagnetic field perturbations to analyze the effect of the correction term…
Probing hairy black holes caused by gravitational decoupling using quasinormal modes and greybody bounds
Yi Yang, Dong Liu, Ali Övgün +2
Gravitational decoupling can add hair to the black holes by adding extra sources. The quasinormal modes of hairy black hole caused by gravitational decoupling for the massless scal…
