Black holes with dark matter halos and a positive cosmological constant: Energy conditions and signatures
Long-Yue Li, Li-Ming Cao, Yungui Gong +3
We study static, spherically symmetric black holes surrounded by dark matter halos in the presence of a positive cosmological constant. Assuming vanishing radial pressure, we deriv…
Quasinormal modes of Schwarzschild--AdS black holes with a near-horizon reflective surface
Libo Xie, Liang-Bi Wu, Yu-Sen Zhou +3
We investigate the scalar quasinormal mode (QNM) spectrum of Schwarzschild-AdS black holes with a partially reflective surface placed near the event horizon. The corresponding QNM…
Global structure and stability of Kerr-Bertotti-Robinson spacetime
Yu-Sen Zhou, Liang-Bi Wu, Ming-Fei Ji +3
The surface of the Kerr-Bertotti-Robinson spacetime is not a genuine boundary. We construct its natural analytic extension and show that of one KBR region is…
The (in)stability on total transmission modes with small bumps
Xi-Ning Dong, Liang-Bi Wu, Yu-Sen Zhou +1
Total transmission modes (TTMs) are a class of reflectionless solutions to black hole perturbation equations, closely related to quasinormal modes (QNMs), and can exhibit significa…
Notes on Kerr-Bertotti-Robinson Spacetime
Yu-Sen Zhou, Liang-Bi Wu, Ming-Fei Ji +3
The surface of the Kerr--Bertotti--Robinson (KBR) spacetime is not the collection of the endpoints of infinitely extended light rays, and the Coulomb type component of g…
Exceptional lines of Reissner-Nordström-de Sitter black hole surrounded by a thin shell of matter
Liang-Bi Wu, Yu-Sen Zhou, Ming-Fei Ji +3
We study the exceptional line (EL) in the quasinormal modes (QNMs) of Reissner-Nordström-de Sitter black hole surrounded by a static thin shell of matter. For a conformally scalar…
Extended parameterized spin expansion formalism for ringdown analysis with GW250114
Jia-Ning Chen, Liang-Bi Wu, Zong-Kuan Guo
Parameterized descriptions of black-hole quasinormal-mode spectra are essential for testing gravity with ringdown observations. We extend the Parameterized Spin Expansion Coefficie…
Total transmission modes in draining bathtub model with vorticity
Zhe Yu, Liang-Bi Wu
We investigate the total transmission modes (TTMs) in the draining bathtub model (DBM) with vorticity using the Chebyshev-Lobatto pseudospectral method, where the boundary conditio…
Virtual absorption modes of Schwarzschild-de Sitter spacetimes in semi-open systems
Liang-Bi Wu, Yu-Sen Zhou, Zhe Yu +3
We present a study of virtual absorption modes (VAMs) in Schwarzschild-de Sitter (SdS) spacetime under semi-open boundary conditions, where the VAMs correspond to total transmissio…
