Critical solutions of scalarized black holes
Jose Luis Blázquez-Salcedo, Sarah Kahlen, Jutta Kunz
We consider charged black holes with scalar hair obtained in a class of Einstein-Maxwell-scalar models, where the scalar field is coupled to the Maxwell invariant with a quartic co…
Quasinormal modes of hot, cold and bald Einstein-Maxwell-scalar black holes
Jose Luis Blázquez-Salcedo, Carlos A. R. Herdeiro, Sarah Kahlen +3
Einstein-Maxwell-scalar models allow for different classes of black hole solutions, depending on the non-minimal coupling function employed, between the scalar field and the…
Polar quasinormal modes of the scalarized Einstein-Gauss-Bonnet black holes
Jose Luis Blázquez-Salcedo, Daniela D. Doneva, Sarah Kahlen +3
We study the polar quasinormal modes of spontaneously scalarized black holes in Einstein-Gauss-Bonnet theory. In previous works we showed that a set of nodeless solutions of the fu…
Axial perturbations of the scalarized Einstein-Gauss-Bonnet black holes
Jose Luis Blázquez-Salcedo, Daniela D. Doneva, Sarah Kahlen +3
We study the axial perturbations of spontaneously scalarized black holes in Einstein-Gauss-Bonnet (EGB) theories. We consider the nodeless solutions of the fundamental branch of th…
Quasinormal modes of dilatonic Reissner-Nordström black holes
Jose Luis Blázquez-Salcedo, Sarah Kahlen, Jutta Kunz
We calculate the quasinormal modes of static spherically symmetric dilatonic Reissner-Nordström black holes for general values of the electric charge and of the dilaton coupling co…
Wormholes Immersed in Rotating Matter
Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2
We consider Ellis wormholes immersed in rotating matter in the form of an ordinary complex boson field. The resulting wormholes may possess full reflection symmetry with respect to…
Radial perturbations of the scalarized EGB black holes
Jose Luis Blázquez-Salcedo, Daniela D. Doneva, Jutta Kunz +1
Recently a new class of scalarized black holes in Einstein-Gauss-Bonnet (EGB) theories was discovered. What is special for these black hole solutions is that the scalarization is n…
Symmetric and Asymmetric Wormholes Immersed In Rotating Matter
Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2
We consider four-dimensional wormholes immersed in bosonic matter. While their existence is based on the presence of a phantom field, many of their interesting physical properties…
Wormholes Immersed in Rotating Matter
Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2
We demonstrate that rotating matter sets the throat of an Ellis wormhole into rotation, allowing for wormholes which possess full reflection symmetry with respect to the two asympt…
Spontaneous Symmetry Breaking in Wormholes Spacetimes with Matter
Christian Hoffmann, Theodora Ioannidou, Sarah Kahlen +2
When bosonic matter in the form of a complex scalar field is added to Ellis wormholes, the phenomenon of spontaneous symmetry breaking is observed. Symmetric solutions possess full…
