Charged Gauss-Bonnet black holes with curvature induced scalarization in the extended scalar-tensor theories
Daniela D. Doneva, Stella Kiorpelidi, Petya G. Nedkova +2
Recently new scalarized black hole solutions were constructed in the extended scalar-tensor-Gauss-Bonnet gravity, where the scalar field is sourced by the curvature of the spacetim…
On the shadow of rotating traversable wormholes
Galin Gyulchev, Petya Nedkova, Vassil Tinchev +1
We revisit the shadow of rotating traversable wormholes discussing the role of the wormhole throat in the shadow formation. For certain classes of wormholes the throat serves as a…
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…
Multiple shadows from distorted static black holes
Jai Grover, Jutta Kunz, Petya Nedkova +2
We study the local shadow of the Schwarzschild black hole with a quadrupole distortion and the influence of the external gravitational field on the photon dynamics. The external ma…
