Quasinormal-Mode Collider Spectroscopy
Mian Zhu, Jun Tao, Peng Wang
Black-hole (BH) quasinormal modes encode the properties of merger remnants and provide powerful tests of strong-field gravity. The BH spectroscopy has predominantly treated them as…
Finite Coherence in Gravitational Waves from Tidally Excited Axion Clouds
Yizhi Liang, Mian Zhu, Wen-Biao Han +3
Axion clouds around rotating black holes form gravitational atoms whose tidal transitions can radiate gravitational waves in binaries. For strongly coupled Bohr crossings, transiti…
Revisiting the Lyth bound constraints on inflation from ACT DR6 results
Rui Yang, Jun Tao, Peng Wang +1
The Lyth bound asserts that the field excursion of inflaton must be sub-Planckian, thereby imposing an upper bound on the amplitude of the tensor power spectrum in inflationary sce…
Exceptional Points in Quasinormal Spectra of Hairy Black Holes
Lang Cheng, Xiaobo Guo, Yuhan Li +2
Exceptional points (EPs) in quasinormal mode (QNM) spectra are non-Hermitian degeneracies at which both the eigenvalues and eigenfunctions coalesce. In this paper, we identify an E…
Coexistence of Spectrally Stable and Unstable Modes in Black Hole Ringdowns
Peng Wang, Tianshu Wu
Recent studies have shown that a secondary potential barrier, forming a potential well outside the event horizon, can destabilize the Quasinormal Mode (QNM) spectrum of black holes…
Gravitational Lensing by Black Holes in Einstein-nonlinear Electrodynamic Theories with Multiple Photon Spheres
Siyuan Hui, Benrong Mu, Peng Wang
In this paper, we study the gravitational lensing effects of non-linear electrodynamic black holes. Non-linear electrodynamic black holes serve as typical models for multi-event ho…
Schwarzschild Black Holes Immersed in Born-Infeld Magnetic Fields and Their Observational Signatures
Yiqian Chen, Guangzhou Guo, Benrong Mu +1
We investigate the influence of Born-Infeld (BI) nonlinear electrodynamics on magnetic field configurations, photon orbits, and black hole shadows for Schwarzschild black holes imm…
Rotating Black Holes in Einstein-Born-Infeld Theory
Lang Cheng, Peng Wang
We numerically construct a family of stationary, axisymmetric black hole solutions in Einstein-Born-Infeld theory, incorporating both electric charge and rotation. Our results indi…
Probing the thermodynamics of charged Gauss Bonnet AdS black holes with the Lyapunov exponent
Xin Lyu, Jun Tao, Peng Wang
In this paper, we investigate the thermodynamic properties of charged AdS Gauss-Bonnet black holes and the associations with the Lyapunov exponent. The chaotic features of the blac…
Echoes from charged black holes influenced by quintessence
Siyuan Hui, Benrong Mu
In this paper, we investigate the effective potential and echoes from the dyonic black hole with quintessence. For a dyonic black hole, the quasi-topological electromagnetism provi…
