Shadows of rotating hairy Kerr black holes coupled to time periodic scalar fields with non-flat target space
Galin N. Gyulchev, Ayush Roy, Lucas G. Collodel +3
We study the shadows cast by rotating hairy black holes with two non-trivial time-periodic scalar fields having a non-flat Gaussian curvature of the target space spanned by the sca…
Magnetized Thick Disks around Boson Stars
Kristian Gjorgjieski, Jutta Kunz, Matheus C. Teodoro +2
The effects of magnetic fields on accretion disks around compact objects are of high importance in the study of their general properties and dynamics. Here we analyze the influence…
Polish Doughnuts around Scalarized Kerr Black Holes
Matheus C. Teodoro, Lucas G. Collodel, Daniela Doneva +3
In this work we aim to investigate non-mainstream thick tori configurations around Kerr Black Holes with Scalar Hair (KBHsSH). For that goal, we provide a first approach using cons…
Retrograde Polish Doughnuts around Boson Stars
Matheus C. Teodoro, Lucas G. Collodel, Jutta Kunz
We investigate Polish doughnuts with a uniform constant specific angular momentum distribution in the space-times of rotating boson stars. In such space-times thick tori can exhibi…
Spin-induced scalarization of Kerr black holes with a massive scalar field
Daniela D. Doneva, Lucas G. Collodel, Christian J. Krüger +1
In the present paper we study the onset of the spin-induced scalarization of a Kerr black hole in scalar-Gauss-Bonnet gravity with a massive scalar field. Our approach is based on…
Spin-induced black hole scalarization in Einstein-scalar-Gauss-Bonnet theory
Emanuele Berti, Lucas G. Collodel, Burkhard Kleihaus +1
We construct black hole solutions with spin-induced scalarization in a class of models where a scalar field is quadratically coupled to the topological Gauss-Bonnet term. Starting…
