Nonsingular black holes and spherically symmetric objects in nonlinear electrodynamics with a scalar field

Antonio De Felice, Shinji Tsujikawa

In general relativity with vector and scalar fields given by the Lagrangian $L (F, ϕ, X)$ , where $F$ is a Maxwell term and $X$ is a kinetic term of the scalar field $ϕ$ , we stu…

Instability of nonsingular black holes in nonlinear electrodynamics

Antonio De Felice, Shinji Tsujikawa

We show that nonsingular black holes realized in nonlinear electrodynamics are always prone to Laplacian instability around the center because of a negative squared sound speed in…

Revisiting linear stability of black hole odd-parity perturbations in Einstein-Aether gravity

Shinji Mukohyama, Shinji Tsujikawa, Anzhong Wang

In Einstein-Aether gravity, we revisit the issue of linear stabilities of black holes against odd-parity perturbations on a static and spherically symmetric background. In this the…

Linear stability of vector Horndeski black holes

Che-Yu Chen, Antonio De Felice, Shinji Tsujikawa

Horndeski's vector-tensor (HVT) gravity is described by a Lagrangian in which the field strength $F_{μν} = \partial_{μ} A_{ν} - \partial_{ν} A_{μ}$ of a vector field $A_{μ}$ interacts with a dou…

Angular and radial stabilities of spontaneously scalarized black holes in the presence of scalar-Gauss-Bonnet couplings

Masato Minamitsuji, Shinji Mukohyama, Shinji Tsujikawa

We study the linear stability of spontaneously scalarized black holes (BHs) induced by a scalar field $ϕ$ coupled to a Gauss-Bonnet (GB) invariant $R_{GB}^{2}$ . For the scalar-GB…

Probing the signature of axions through the quasinormal modes of black holes

Antonio De Felice, Shinji Tsujikawa

The axion-photon coupling allows the existence of a magnetically and electrically charged black hole (BH) solution endowed with a pseudo-scalar hair. For the Reissner-Nordstrom BH…
