This article is based upon work from COST Action CA18108, supported by COST (European Cooperation in Science and Technology) .We construct an axially symmetric solution of Eddington-inspired Born-Infeld gravity coupled to an electromagnetic field in 2 + 1 dimensions including a (negative) cosmological constant term. This is achieved by using a recently developed mapping procedure that allows to generate solutions in certain families of metric-affine gravity theories starting from a known seed solution of General Relativity, which in the present case corresponds to the electrically charged Banados-Teitelboim-Zanelli (BTZ) solution. We discuss the main features of the new configurations, including the modifications to the ergospheres and horizons, the emergence of wormhole structures, and the consequences for the regularity (or not) of these space-times via geodesic completeness.engjournal articlehttp://dx.doi.org/10.1088/1475-7516/2021/11/025https://iopscience.iop.org/open access51-73TimeFísica-Modelos matemáticosFísica matemática
