Charged Superradiant Instability of Spherically Symmetric Regular Black Holes in de Sitter Spacetime: Time- and Frequency-Domain Analysis
Yizhi Zhan, Hengyu Xu, Haowei Chen +1
We investigate the superradiant instability of Ayón-Beato-García-de Sitter (ABG-dS) black holes under massless charged scalar perturbations using both time-domain evolutions and fr…
Electric Penrose process in spherically symmetric regular black holes with and without a cosmological constant
Haowei Chen, Hengyu Xu, Yizhi Zhan +1
We investigate the electric Penrose process in Ayón-Beato-García (ABG) black holes, both in the presence and absence of a cosmological constant, presenting, to the best of our know…
Charged superradiant instability in a spherical regular black hole
Yizhi Zhan, Hengyu Xu, Shao-Jun Zhang
We examine the stability of a spherically symmetric regular black hole when subjected to perturbations from a charged scalar field. This particular black hole is constructed by def…
Tachyonic instability and spontaneous scalarization in parameterized Schwarzschild-like black holes
Hengyu Xu, Yizhi Zhan, Shao-Jun Zhang
We study the phenomenon of spontaneous scalarization in parameterized Schwarzschild-like black holes. Two metrics are considered, the Konoplya-Zhidenko metric and the Johannsen-Psa…
