Abstract: Recently, numerical solutions to the field equations of Einstein-scalar--Gauss-Bonnet (EsGB) gravity that correspond to black holes with nontrivial scalar hair have been reported. Here, we employ the method of the continued-faction expansion in terms of… read more here.

Abstract: We present an infinite class of one-parameter scalar field extensions to the Banados, Teitelboim and Zanelli (BTZ) black hole in 2 + 1 dimensions. By virtue of the scalar charge, the thin-shell wormhole supported by… read more here.
