Planar black holes and wormholes with a flat exterior
Hideki Maeda, Cristian Martinez
We present -dimensional planar black holes and wormholes with a flat exterior, which are originated by an exact solution in general relativity. The nonvacuum regions of t…

Exact plane symmetric black bounce with a perfect-fluid exterior obeying a linear equation of state
Hideki Maeda, Cristian Martinez
We investigate an exact two-parameter family of plane symmetric solutions admitting a hypersurface-orthogonal Killing vector in general relativity with a perfect fluid obeying a li…

Existence and absence of Killing horizons in static solutions with symmetries
Hideki Maeda, Cristian Martinez
Without specifying a matter field nor imposing energy conditions, we study Killing horizons in -dimensional static solutions in general relativity with an -dimensi…
