Black hole minimum size and scalar charge in shift-symmetric theories
Farid Thaalba, Georgios Antoniou, Thomas P. Sotiriou
It is known that, for shift-symmetric scalars, only a linear coupling with the Gauss-Bonnet invariant can introduce black hole hair. Such hairy black holes have a minimum mass, det…
Constraining modified gravity theories with scalar fields using black-hole images
Georgios Antoniou, Alexandros Papageorgiou, Panagiota Kanti
We study a number of well-motivated theories of modified gravity with the common overarching theme that they predict the existence of compact objects such as black holes and wormho…
Stable spontaneously-scalarized black holes in generalized scalar-tensor theories
Georgios Antoniou, Caio F. B. Macedo, Ryan McManus +1
It has been shown that the synergy of a scalar field coupling with both the Ricci scalar and the Gauss-Bonnet invariant significantly affects the properties of scalarized black hol…
