Time-domain analysis of scalar perturbations of Kerr--Newman black holes with Chern--Simons and Maxwell couplings
Yan-Ming Chen, Hyat Huang, Meng-Yun Lai +3
To study the onset of scalarization, we investigate linear scalar perturbations around Kerr--Newman black holes in the Einstein-Chern-Simons-Maxwell-scalar theory with quadratic Ch…
Critical Scalarization for a Self-Gravitating Bosonic Condensate
Meng-Yun Lai, Hyat Huang, Wen-Cong Gan +2
We establish a minimal nonrelativistic realization of scalarization in a self-gravitating bosonic condensate coupled to a scalar response field. A local effective-mass shift and no…
Light rings and optical appearances of naked singularities, solitons, and black holes in beyond Horndeski gravity
Hyat Huang, Jutta Kunz, Rashmi Uniyal +1
We investigate the geodesic structure and optical appearance of compact objects with primary scalar hair in shift- and parity-symmetric beyond Horndeski gravity. The analytic solut…
Spin-Induced Nonlinear Scalarization of Kerr Black Holes in Einstein-scalar-Gauss-Bonnet Gravity
Meng-Yun Lai, Hyat Huang, Jutta Kunz +2
We investigate spin-induced scalarization of Kerr black holes in an Einstein-scalar-Gauss-Bonnet (EsGB) model that does not admit a linear tachyonic instability of the scalar-free…
Thermodynamics and phase transitions of nonlinearly scalarized black holes in Einstein-scalar-Gauss-Bonnet theory
De-Cheng Zou, Xu Yang, Meng-Yun Lai +2
We investigate the thermodynamic properties of static nonlinearly scalarized black holes in Einstein-scalar-Gauss-Bonnet theory with polynomial coupling functions. Based on the sca…
Phase Structure of Scalarized Black Holes in Einstein-Scalar-Gauss-Bonnet Gravity
Carlos Herdeiro, Hyat Huang, Jutta Kunz +3
We revisit scalarized black holes in Einstein-scalar-Gauss-Bonnet gravity and analyze the thermodynamic phase transition between the Schwarzschild solution of general relativity an…
On Coordinate Singularities Induced by Trapping Horizons
Jinbo Yang, Hongwei Tan, Hyat Huang +1
The trapping (or apparent) horizon serves as a key tool for tracing the complete evolution of black holes. We investigate a class of coordinate singularities induced by such trappi…
